Stereochemical Aspects of the Reactionand Preparation of the Two Enantiomers of Useful C4 BifunctionalChiral Synthons. — Baker’s yeast mediated reduction of variousphenylthio- or phenylsulfonyl-functionalized methacrolein derivatives (I), (IV),and (V) provides access to enantioenriched sulfur-functionalized C4-buildingblocks (II) and (III). It is shown that extent and sense of stereoinduction stronglydepend on the structure of methacrolein derivative and on the oxidation stateof the sulfur. — (SERRA, STEFANO; FUGANTI, CLAUDIO; Tetrahedron:Asymmetry 12 (2001) 15, 2191-2196; Dip.
