Abstract
Porcine liver eaterase (PLE)- or rabbit liver eaterase (RLE)-catalyzed hydrolysis of the pro-S eater group of diethyl alpha-alkyl-alpha -(be nzyloxycarbonylamino)malonate s 2a-e afforded (R)-ethyl alpha-alkyl-al pha -(benzyloxycarbonylamino)malonates 3a-e each in excellent enantiom eric excess. Enantiodivergent reductions of these acid eaters 3a-e rea dily furnished both the corresponding enantiomeric alpha-substituted s erines (R)- and (S)-5a-c. (C) 1998 Elsevier Science Ltd.
