Various aryl substituted enones are reduced using lithium aluminum hydride to afford sterioselectively trans substituted alkanols. Mechanistic studies demonstrate 1,2 addition followed by hydroxy-directedhydroalumination of the conjugated styryl unit.

Lipase-mediated acetylation of four diastereomeric and enatiomeric isomers of 3-substituted cyclohexanols 2 has led to an efficient resolution to provide a single stereoisomer, (1R,3S)-cyclohexyl acetate (1R,3S)-3 in a high enantiomeric excess. (C) 1998 Elsevier Science Ltd. All rights reserved.
A new paradigm for biohydroxylation by Beauveria bassiana ATCC 7159

日期:1999.6
The biohydroxylation of a series of amides and related amino, keto and hydrocarbon substrates by the fungal biocatalyst Beauveria bassiana ATCC 7159 has been examined. The product distributions, together with data obtained from selective inhibition experiments using the cyt.P-450 inhibitors isosafrole, 1-aminobenzotriazole and phenylacetylene, suggest that B. bassiana contains a range of hydroxylase enzymes with different substrate specificities. A paradigm is presented for the interpretation of the results of microbial hydroxylation and for the application of existing active site models for B. bassiana. (C) 1999 Elsevier Science Ltd.
