An efficient synthesis of an enantiomerically pure phosphonate analogue of l-GABOB
摘要:
Two reliable methods for the synthesis of the enantiomerically pure (S)-3-amino-2-hydroxypropylphosphonic acid (a phosphonate analogue Of L-GABOB) from diethyl (S)-2,3-epoxypropylphosphonate are elaborated. The amplification of the enantiomeric purity of the intermediate diethyl (S)-3-(tert-butoxycarbonylamino)- and (S)-3-(diphenylmethylamino)-2-hydroxy-propylphosphonates was observed on a silica get column.
