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.

uncontrollable diastereoselectivity because of the absence of reagent–substrate interactions. In this report, stereochemical modulation was accomplished by taking advantage of the pyridine-boryl radical, which leaves the synthetically modifiable boronate moiety on the carbonyl oxygen near the reacting center during the stereo-determining cyclization step. In consequence, a catalytic diastereoselective synthesis

On the baker's yeast mediated transformation of α-bromoenones. Synthesis of (1S,2R)-2-bromoindan-1-ol and (2S,3S)-3-bromo-4-phenylbutan-2-ol
Fermenting baker's yeast converts alpha-bromo substituted enones 7 and 10 into enantiomerically pure (1S,2R)2-bromoindan-1-ol 3 and (2S,3S)-3-bromo-4-phenylbutan-2-ol 11, respectively, through the intermediacy of the corresponding saturated ketones. Structurally related 16 provides the (2R)-allylic alcohol 17 prevalently. (C) 1998 Elsevier Science Ltd. All rights reserved.
