| abstract | The invention comprises steroids of the formula <FORM:1061687/C2/1> (wherein R is hydrogen, A or A.CO and R1 and R11 are hydrogen or A, A being C1- 7 alkyl) and the preparation of the 3b -amino-17b -carbalkoxyandrost-5-enes by reacting a 6b -alkoxy-17b -carbalkoxy-3a ,5a -cycloandrostane with hydrazoic acid in a non-polar, inert, anhydrous, organic solvent and in the presence of an acid catalyst, separating the formed 3b -azido-17b -carbalkoxyandrost-5-ene and reducing this. The products can be acylated or alkylated at the amino group and hydrolysed to 17b -carboxy-compounds which can be re-esterified. Examples are given. 6b - Methoxy - 17b - carbomethoxy - 3a ,5a - cycloandrostane is prepared by refluxing 3b -p-toluenesulphonyloxy - 17b - carbomethoxy - androst-5-ene with sodium acetate and methanol. |
