Synthetic studies in salamander alkaloids
Part I, describes an efficient four step method to effect an unsymmetric ring cleavage between carbons 2 and 3 in the A ring of 17β-acetoxy-5β-androstan-3-one (81b). Bromination of 81b followed by treatment with sodium acetate in refluxing acetic acid gave 2β,17β-diacetoxy-5β-androstan-3-one (159)...
