Enzyme-catalyzed Dediastereomerization of Dibenzylbutanolides by Plant Cell Cultures
摘要:
We have been developed a novel biocatalytic dediastereornerization method, i. e., reactions allowing the transformation of two diastereorners into one diastereomer in quantitative yield. When a mixture of two diastereomers (4R*-5) and (4S*-5) (1:1 ratio) was subjected to Catharanthus roseus cells in B5 medium, dediastereornerization took place to give a single diastereomer (4R*-5) in 80 % chemical yield with 100 % diastereomeric excess and 0 % enantiomeric excess.
