摘要

In order to provide ready access to multigram quantities of the optically pure bremazocines [(−)-and (+)-9, 9-dimethyl-5-ethyl-2-hydroxy-2-(1-hydroxy-cyclopropylmethyl)-6, 7- benzomorphan)], we have developed an improved non-chromatographic synthesis, and determined the optical purity of their N-nor precursors using a rapid and relatively simple 1H NMR method based on diastereomeric derivatization with optically pure 1- ...
