Stereoselective synthesis of petrosterol and a formal synthesis of aragusterols

Stereoselective construction of a steroidal side chain containing a 26-27 cyclopropane ring, compound 22, has been achieved by an intramolecular cyclisation of the corresponding β-methylsulfonyloxy cyanide 16, derived from a chiral cyclopentane derivative. Compound 22 has been further utilised in the synthesis of the naturally occurring steroid petrosterol 3.
