(Z)-alpha-[(Benzyloxy)- or (tert.-butyloxy)carbonylamino]-beta (thienyl)- or (furyl)-acrylic acids and their esters were prepared by known methods and hydrogenated to the corresponding optically active alanine derivatives with optical yields in the range of 58-93% ee using the cationic rhodium complex of "PROPRAPHOS".
(Z)-α-[(苄氧基)-或(叔丁氧基)羰基氨基]-β-(噻吩基)-或(呋喃基)-丙烯酸及其酯通过已知方法制备,并使用“PROPRAPHOS”的阳离子铑配合物将其氢化为相应的光学活性丙氨酸衍生物,光学产率在58 - 93% ee范围内。
