A method for chiral inversion of optically pure or optically enriched mixtures of (S)-(+)-10,11-dihydro-10-hydroxy-5H-dibenz/b,f/azepine-5-carboxamide (I) and (R)-(-)-10,11dihydro-10-hydroxy-5H-dibenz/b,f/azepine-5-carboxamide (II) with a carboxylic acid nucleophile in the presence of a trisubstituted phosphine and a disubstituted azodicarboxylate in a substantially inert solvent is disclosed.
一种用于手性反转的方法,包括在基本惰性溶剂中,以存在三取代膦和二取代偶氮二羧酸酯的情况下,利用羧酸亲核试剂对光学纯或光学富集的(S)-(+)-10,11-二氢-10-羟基-5H-二苯并/b,f/氮杂七环-5-羧酰胺(I)和(R)-(-)-10,11-二氢-10-羟基-5H-二苯并/b,f/氮杂七环-5-羧酰胺(II)进行手性反转。
