✦ Synopsis


Reduction of ethyl 2-allyl-3-oxobutanoate by an enzyme fraction obtained from bakers' yeast results in the formation of ethyl (a,%)-sun-2-allyl-3-hydroxybutanoate in an excellent stereoselectivity.

Diastereomerically

as well as enantiomerically pure 2-allyl-3-hydroxy-

Baker's Yeast Mediated Enantiospecific Synthesis of anti-(2R,3R)p-Chloro-3-hydroxytyrosine: An Ξ±-Amino-Ξ²-hydroxy Acid of Vancomycin. -The synthesis of the protected derivative (V) is achieved via baker's yeast-mediated reduction of the Ξ±-azido-Ξ²-keto ester (II) at pH 4.0. At pH 7.0 the enantioselect
