Stereoselective synthesis of delta-amino-alpha,beta,gamma,delta-unsaturated cycloketones via Mannich-type reaction

A new Mannich-type reaction of aryl propiolaldehydes with benzofuran-3(2H)-one and cyclic secondary amines was established, enabling a completely stereoselective protocol to access a series of unreported delta-amino-alpha,beta,gamma,delta-unsaturated cycloketones in generally good yields. This approach could tolerate various cyclic secondary amines including four-, five-, six-membered and bicyclic rings with water as a major by-product. (C) 2020 Elsevier Ltd. All rights reserved.

Total Synthesis of (+/-)-Liphagal via Organic-Redox-Driven Palladium-Catalyzed Hydroxybenzofuran Formation

A synthetic route to liphagal, a natural PI3K alpha inhibitor isolated from Aka coralliphaga, was established. The present route features an organic redox process where an alkynylquinone undergoes reductive cyclization in the presence of a hydroquinone derivative such as hydroxyquinol (1,2,4-benzenetriol) and catalytic PdCl2 to provide a substituted benzofuran suitable for accessing the natural product. The benzofuran formation takes place via the redox transformation between the alkynylquinone and the electron-rich hydroquinones followed by the concomitant Pd(II)-catalyzed oxycyclization of the resultant alkynylhydroquinone.

A Comparative Study of the Anticancer Activity and PARP-1 Inhibiting Effect of Benzofuran-Pyrazole Scaffold and Its Nano-Sized Particles in Human Breast Cancer Cells

Breast cancer is considered the most common and deadly cancer among women worldwide. Nanomedicine has become extremely attractive in the field of cancer treatment. Due to the high surface to volume ratio and other unique properties, nanomaterials can be specifically targeted to certain cells and tissues to interact with the living systems. The strategic planning of this study is based on using the nanoprecipitation method to prepare nanoparticles BZP-NPs (3.8-5.7 nm) of the previously prepared benzofuran-pyrazole compound (IV) BZP which showed promising cytotoxic activity. The capacity of BZP and BZP-NPs to suppress the growth of human breast tumor MCF-7 and MDA-MB-231 cells was evaluated using MTT assay. The IC50 doses of BZP and BZP-NPs targeting normal breast cells MCF-12A exceeded those targeting the cancer cells by >1000-fold, demonstrating their reasonable safety profiles in normal cells. Furthermore, cell cycle analysis, apoptosis induction detection, assessment of p53, Bcl-2, caspase-3, and PARP-1 levels of BZP and its nano-sized-BZP-NPs particles were also evaluated. Although the obtained results were in the favor of compound IV in its normal-sized particles, BZP-NPs appeared as a hit compound which showed improved cytotoxicity against the tested human breast cancer cells associated with the induction of pre-G1 apoptosis as well as cell cycle arrest at G2/M phase. The increase in caspase-3 level, upregulation of p53, and downregulation of Bcl-2 protein expression levels confirmed apoptosis. Furthermore, ELISA results exhibited that BZP-NPs produced a more favorable impact as a PARP-1 enzyme inhibitor than the parent BZP.

Unexpected Dual Acylation of Naphtho[2,1-b]furan at the Aryl and Hetaryl Ring: Experimental and Theoretical Study

Depending on the reaction conditions, the acylation of 2-ethylnaphtho[2,1-b]furan leads to the formation of a mixture of 1-acetyl-, 5-acetyl-, and 1,5-diacetyl derivatives with a widely varying ratio of components, the structure of which has been characterized by IR and NMR spectroscopy, mass spectrometry, and X-ray diffraction analysis methods. Quantum-chemical simulations using the DFT B3LYP/6-311++G** method have reproduced the experimental geometry of isomeric acetyl[2,1-b]furans and indicated their close thermodynamic stability. However, the Fukui indices of the reactivity f(-) have indicated the preference of the primary attack of the electrophile at the C-5 position (f(-) = 0.18) as compared to the C-1 position (f(-) = 0.06).

Discovery of Diphenoxy Derivatives with Flexible Linkers as Ligands for beta-Amyloid Plaques

The highly rigid and planar scaffolds with pi-conjugated systems have been widely considered to be indispensable for beta-amyloid (A beta) binding ligands. In this study, a library of diphenoxy compounds with different types of more flexible linkers as A beta ligands were synthesized and evaluated. Most of them displayed good affinity (K-i < 100 nM) for A beta(1-42) aggregates, and some ligands even showed values of K-i less than 10 nM. Structure-activity relationship analysis revealed that modification on the linkers or substituents tolerated great flexibility, which challenged the long-held belief that rigid and planar structures are exclusively favored for A beta binding. Three ligands were labeled by iodine-125, and they exhibited good properties in vitro and in vivo, which further supported that this flexible scaffold was potential and promising for the development of A beta imaging agents.

alpha-Lithiobenzyloxy as a Directed Metalation Group in ortho-Lithiation Reactions

The alpha-lithiobenzyloxy group, easily generated from aryl benzyl ethers by selective alpha-lithiation with t-BuLi at low temperature, behaves as a directed metalation group (DMG) providing a direct access to o-lithiophenyl alpha-lithiobenzyl ethers. This ortho-directing effect is reinforced in substrates bearing an additional methoxy group at the meta position. The generated dianions can be reacted with a selection of electrophiles including carboxylic esters and dihalosilanes or germanes, which afford interesting benzofuran, sila(germa)dihydrobenzofuran, and silachroman derivatives from simple aryl benzyl ethers.

Cut and sew: benzofuran-ring-opening enabled cyclopentenone ring formation

A facile approach to the fully substituted cyclopentenones involving an unprecedented benzofuran-ring-opening is described. The cleavage of a benzofuran endocyclic C2-O bond proceeded smoothly in the absence of any transition metal catalyst or highly reactive organometallic reagent. Such benzofuran-ring-opening is delicately incorporated into an acid-catalyzed cascade process, orchestrating a novel synthetic strategy for complex cyclopentenones with excellent yields and diastereoselectivities.

Tailoring a stable and recyclable nanobiocatalyst by immobilization of surfactant treated Burkholderia cepacia lipase on polyaniline nanofibers for biocatalytic application

Polyaniline nanofibers were synthesized by the oxidative polymerization of aniline. Surfactant treated lipase from Burkholdaria cepacia was immobilized on these polyaniline nanofibers by adsorption. The activity of immobilized preparation was six times higher than that of free lipase with an enhanced dispersion in organic sol- vents. Five-level-four-factor central composite design was applied for the optimization of immobilization parameters (viz. reaction time, pH, stirring rate and enzyme-support ratio) which were evaluated on the basis of lipase loading and activity. The thermal stability of the lipase in the nanobioconjugate, demonstrated in terms of the half-life at 80 degrees C was almost sixteen-fold higher than in the free form. The reusability data revealed the utility of the nanoconjugate for seven consecutive cycles with a slow and gradual decline in the activity. However, the nanoconjugate retained almost 30% of their initial activity after seven cycles of reuse revealing its utility of in industrial applications. The nanoconjugate was used in the kinetic resolution of (RS)-1-(7-(3-chloro-2-hydroxypropoxy)benzofuran-2-yl) ethanone, racemic intermediate of an important beta-blocker (Befunolol), with a high conversion rate of 48.2%, 98% ee-value and enantioselectivity (E) of 188, which signify its importance as a nanobiocatalyst.
