The partial synthesis of pollinastanol (14) from cycloartanol (3) is reported. The transformation proceeds through the methylenic intermediate 12; the ring enlargement with cyanogen azide affords pollinastanone (13) further reduced to 14, The 4‐keto isomer of pollinastanone (17) as well as a series of 5‐β isomeric compounds are also described.
