Abstract
Abstract Die Desulfurierung der Titelverbindung (I) führt über die zwei möglichen, intermediären Diastereoisomeren (IIa) und (IIb) zu der (3R)‐ und der (3S)‐Isopropyl‐2‐oxo‐piperazin‐(6S)‐carbonsäure (IIIa) bzw. (IIIb), die als Methylester ihrer N‐Ben.zyloxycarbonyl‐Derivate (IIIc) im Verhältnis 6:4 erhalten werden.
