Montmorillonite K-10 clay as reusable heterogeneous catalyst for the microwave-mediated solventless synthesis of phthalazinetetraones

Different phthalazino[2,3-b]phthalazine-5,7,12,14-tetraones were synthesized in a simple and environmentally benign method from the reaction of some phthalic anhydrides with semicarbazide or thiosemicarbazide using montmorillonite K-10 clay as solid heterogeneous acidic catalyst and microwaves under solvent-free conditions in good yields and short reaction times. The present method has many obvious advantages compared with those reported in the literature, including high efficiency, higher yield, operational simplicity, environmental benignity, and the possibility of recycling the solid clay. The solid clay catalyst used in the first cycle of the reactions was successfully recovered and reused in the second cycle, showing a gradual decrease in activity.

Transpositive Tandem Annulation of Phthalides with Allene Carboxylates: Regioselective Synthesis of Arylnaphthalene Lignans

Allene carboxylates, scarcely used as Michael acceptors, serve as acceptors in the annulation with phthalides in the presence of LDA and provide a one-pot synthesis of naphtho[c]furanones in very good yields. This tandem annulation is proposed to proceed via transposition of the hydroxy group resulting from the initial annulation.

Synthesis and study of the properties of thermoset oligoimides with propargyl fragment

A series of thermoplastic oligoimides with a propargyl substituent in the side chain was synthesized by the method of high-Temperature catalytic copolycondensation in the melt of benzoic acid based on the monomer 5-(2-propyn-1-yloxy) benzene-1,3-diamine (PBD), 2,2-bis-[(3,4-di-carboxyphenoxy)phenyl]propane dianhydride (BPADA), 2,2-bis-[(4-Aminophenoxy)phenyl]propane (BAPP) and phthalic anhydride (PA). The uncured imide oligomers showed good solubility (>20 wt% in N-methyl-2-pyrrolidone), wide temperature processing window (>50C) and also flow well at 220C. These imide oligomers were successfully converted to cross-linked structures after curing at 300C. Cross-linked oligomers have a temperature of 5% weight loss >500C and Tg >200C.

Rhodium(III)-catalyzed C-H activation/annulation with vinyl esters as an acetylene equivalent

The behavior of electron-rich alkenes in rhodium-catalyzed C-H activation/annulation reactions is investigated. Vinyl acetate emerges as a convenient acetylene equivalent, facilitating the synthesis of sixteen 3,4-unsubstituted isoquinolones, as well as select heteroaryl-fused pyridones. The complementary regiochemical preferences of enol ethers versus enol esters/enamides is discussed.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.HPLC of Formula: C9H6O3, you can also check out more blogs about496-41-3

Virtual screening-driven discovery of dual 5-HT6/5-HT2A receptor ligands with pro-cognitive properties

A virtual screening campaign aimed at finding structurally new compounds active at 5-HT6R provided a set of candidates. Among those, one structure, 4-(5-{[(2-{5-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl}ethyl)amino]methyl}furan-2-yl)phenol (1, 5-HT6R Ki = 91 nM), was selected as a hit for further optimization. As expected, the chemical scaffold of selected compound was significantly different from all the serotonin receptor ligands published to date. Synthetic efforts, supported by molecular modelling, provided 43 compounds representing different substitution patterns. The derivative 42, 4-(5-{[(2-{5-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl}ethyl)amino]methyl}furan-2-yl)phenol (5-HT6R Ki = 25, 5-HT2AR Ki = 32 nM), was selected as a lead and showed a good brain/plasma concentration profile, and it reversed phencyclidine-induced memory impairment. Considering the unique activity profile, the obtained series might be a good starting point for the development of a novel antipsychotic or antidepressant with pro-cognitive properties.

Ozone as a tool for studying stress responses in tomato: Signalling and defence in normal and mutant lines

Research increasingly converges on the concept that ozone (O3) behaves as an abiotic elicitor in plants, and this suggests the possibility of using such photochemical oxidant as an experimental tool for studying plant defence responses towards biotic and abiotic stresses. The vast array of molecular events deployed upon exposure to O3 are thought to be mediated by a complex cross-talk among hormonal signalling routes, in which ethylene, salicylic acid and (-)-jasmonic acid participate. In the present contribution, a first set of results concerning signalling and defence in tomato mutant lines impaired in ethylene perception (Never ripe) or biosynthesis (ripening inhibitor) after exposure to realistically elevated O3 as a model Stressor, are presented. Differences in terms of temporal activation and relative transcripts abundance of the ethylene biosynthetic enzymes 1-aminocyclopropane-1-carboxylic acid (ACC) synthase and ACC oxidase, as well as of the ethylene receptor NR, were observed among the two aforementioned mutants and their common near isogenic wild type. Since the three genotypes compared were equally damaged by the treatment, a sort of isoform ” compensation” among ethylene biosynthetic genes could be hypothesised, with the common aim of producing an ethylene burst triggering defence responses. Such a burst was indeed observed and showed similar time patterns in the three genotypes, although the peak ethylene emission levels were different.
