AB  - In the present paper, the preparation of 3β-hydroxy-17β-dimethyl- tert-butylsilyloxy-5-azaandrostane (15) in fourteen steps is described. B-nor-17-oxoandrost-5-en-3β-yl acetate (1) 1,2 was used as the starting material, which was transformed to the key intermediate of the synthesis, B-nor-17β-dimethyl-tert-butylsilyloxyandrost-4-en-3β-yl acetate (7).

AB  - A simple one-put procedure for the synthesis of the 5,6-seco-steroidal acids 9a,b in described in this paper. It consists of the epoxidation of the ▲ 5 -steroids, i.e., cholesteryl acetate (8a) and 17-oxo-aandrost-5-en-3β-yl acetate (8b) with peracetic acid (generated in situ by the H 2 WO 4 H 2 O 2 system), followed by the CrO 3 /H 2 SO_ oxidation of the thus formed epoxides. The 5,6-seco-steroidal acids 9a,b (obtained in about 90% and 77% yield, respectively) are transformed to the corresponding B-norsteroids by the known method (Beayer-Villiger oxidation and subsequent thermolysis of the respective β-lactones).
