Oxidation of ergosterol acetate with chromic anhydride

  • Published:
Chemistry of Natural Compounds Aims and scope

Summary

  1. 1.

    The conditions for the oxidation of ergosterol acetate with chromic anhydride have been studied, and it has been shown that the yield of the 3β-acetoxy-5α-hydroxyergosta-7,22-dien-6-one (Burawoy's ketone) so obtained is a maximum when oxidation is performed in ether.

  2. 2.

    On the basis of the results obtained, a multistage mechanism for the oxidation of ergosterol acetate is suggested.
