Abstract
An efficient new procedure for the degradation of cyclolaudenyl acetate to 3 β - acetoxy - 4,4,14α -trimethyl - 9, 19 - cyclo - 5α - pregnan - 20 - one and/or 3 β - acetoxy - 4,4,14 α- trimethyl - 9,19 - cyclo - 5 α -androstan - 17 - one is described. The key-step is simultaneous base-catalysed dehydrohalogenation and isomerisation of the resulting olefin, of a suitably derived halide.
