Efficient Synthesis of Benzofurans via Cross-Coupling of Catechols with Hydroxycoumarins Using O-2 as an Oxidant Catalyzed by AlPO4-Supported Rh Nanoparticle

An efficient synthesis of benzofuran derivatives via the cross-coupling of catechols and hydroxycoumarins in H2O using O-2 as an ideal oxidant is reported. The above reaction allows the direct use of substrates without prefunctionalization, involves formation of C-C and C-O bonds in cascade manner, and affords H2O as the sole by-product. This simple and clean reaction is achieved by the development of an AlPO4-supported Rh nanoparticle catalyst. The catalyst was applicable to the synthesis of a wide range of benzofurans. We also successfully utilized this catalytic method for total synthesis of flemichapparin C, one of the naturally occurring coumestans exhibiting bioactivity. The combined functions of Rh nanoparticles and AlPO4 play a key role in this reaction where in situ generated o-benzoquinone by Rh nanoparticles is possibly an intermediate for nucleophilic addition to hydroxycoumarins on AlPO4.

Benzo[a]pyrene and 2,3-benzofuran induce divergent temporal patterns of AhR-regulated responses in zebrafish embryos (Danio rerio)

Biotests like the fish embryo toxicity test have become increasingly popular in risk assessment and evaluation of chemicals found in the environment. The large range of possible endpoints is a big advantage when researching on the mode of action of a certain substance. Here, we utilized the frequently used model organism zebrafish (Danio rerio) to examine regulative mechanisms in the pathway of the aryl-hydrocarbon receptor (AHR) in early development. We exposed embryos to representatives of two chemical classes known to elicit dioxin-like activity: benzo[a]pyrene for polycyclic aromatic hydrocarbons (PAHs) and 2,3-benzofuran for polar O-substituted heterocycles as a member of heterocyclic compounds in general (N-, S-, O-heterocycles; NSO-hets). We measured gene transcription of the induced P450 cytochromes (cyp1), their formation of protein and biotransformation activity throughout the whole embryonic development until 5 days after fertilization. The results show a very specific time course of transcription depending on the chemical properties (e.g. halogenation, planarity, K-ow), the physical decay and the biodegradability of the tested compound. However, although this temporal pattern was not precisely transferable onto the protein level, significant regulation in enzymatic activity over time could be detected. We conclude, that a careful choice of time and end point as well as consideration of the chemical properties of a substance are fairly important when planning, conducting and especially evaluating biotests.

Regio- and Stereoselective Synthesis of Allylic Spiroethers (Spirobenzofuranes) via an Intramolecular Mizoroki-Heck Reaction

The palladium(0)-catalyzed intramolecular annulation of 12 1,3-disubstituted cyclopentenes, derived from (+)-vincelactam, resulted in 5-exo cyclizations which furnished a series of 2,5-dimethyl-14(3R,4’S)-2H-spiro[benzofuran-3,1′-cyclopentan]2′-en-4′-yl)-1H-pyrroles in excellent diastereoselectivities and useful isolated yields. The double bond migration process that followed the arylpalladium insertion was controlled by a fine-tuning of the reaction system, which provided regioselectivities of up to 98:2. The selective Mizoroki-Heck reaction was used as the key transformation for preparing two new spirocyclic monoprotected amino acids as single stereoisomers.

Online fast pyrolysis of cellulose over titanium dioxide using tandem micro -reactor -GC -MS

In this work, the catalytic effect of titanium dioxide (TiO 2 ) on the online fast pyrolysis of cellulose was inves- tigated using a tandem micro reactor coupled to a gas chromatograph-mass spectrometer (GC -MS) system. This system was used in the following two different modes: in -situ and ex -situ . The results obtained with TiO 2 were compared with those of zeolite (HZSM-5) under identical pyrolysis conditions. Levoglucosan was the major product in the non -catalytic pyrolysis of cellulose. As for the catalytic pyrolysis of cellulose at 500 ? C with TiO 2 ( in -situ ), the peak of levoglucosan disappeared whereas aromatic hydrocarbons such as benzene, toluene and naphthalene were newly detected. In this case, oxygenated compounds such as furfural, furan, methylfuran were still observed for TiO 2 whereas oxygenated compounds (i.e, furan, benzofuran, methylbenzofuran, acetone and 2-butanone) with low yields were observed for in -situ catalytic pyrolysis with HZSM-5. For ex -situ catalytic py- rolysis of cellulose at 500 ? C using TiO 2 , oxygen -containing compounds were hardly formed, while various ar- omatic hydrocarbons were detected. When the ex -situ pyrolysis of cellulose with HZSM-5 was carried out, the yields of the aromatic hydrocarbons were comparable to those with TiO 2 .
