The preparation of 16β-piperidino- and -morpholino-17-ketones of C18- and C19-steroids from 16α-bromo-17-ketones is described; reduction gives the corresponding cis-16β-amino-17β-ol the structure of which is confirmed by preparation from the trans-16α-bromo-17β-ol and by infrared spectroscopy. trans-16-Amino-17ols were prepared from cis-16-bromo-17-ols and a 16α,17α-epoxide.
