Abstract
A number of steroids containing cyclic amino functions have been prepared and studied for biological activities, and some of them have proved to be clinically useful as a neuromuscular blocking agent, an antitumour agent, and so on.1 As the conventional methods, the reactions of cyclic amines with halides2 or epoxides,3 the reductive amination of ketones,4 and the reduction of enamines5 have been widely used for introducing these amino functions into steroid nucleus.
