Abstract

Abstract Die bei der Kondensation von DL-Cystein (DL-1) mit D-(+)-Galactose (2) entstehenden zueinander diastereomeren 4-Thiazolidincarbonsäuren 3 und 4 lassen sich durch Kristallisation trennen. Bei der Ringspaltung von 3 bzw. 4 entstehen L-Cystein (L-1) bzw. D-Cystein (D-1). Statt D-(+)-Galactose kann man auch andere chirale Aldosen einsetzen.
