The short synthetic route from 3β-acetoxy-5β-methyl-19-norcholest-9(10)-en-6-one (1) to 8-methylene-des-AB-cholestan-9-one (8) is described.Compound 8 is a convenient intermediate for synthesis of relatives of vitamin D3 by the A CD route.

, p. 4243 - 4244 (2007/10/02)
The efficient degradation of 1 to the α-methylene ketone 4 is described.Compound 4 was then converted to the allylic alcohol 8a- the precursor of vitamin D3 relatives.
