Abstract
The two aminoketones 12α-amino-3α,20β-diacetoxy-11-keto-5β-pregnane and 9α-amino-3β,20β-diacetoxy-11-keto-5α-pregnane were prepared. Deamination of the former could be controlled to give either 12-methyl-18-norpregnane derivatives or C-nor-D-homo (12,14-cyclo-13,14-secopregnane)derivatives. Deamination of the 9α-aminoketone gave a series of 9β-methyl-19-norsteroids.Keywords
