Abstract
The oxidation of ergosterol in methylcyclohexane with aqueous permanganate affords 3β,5α,6α-trihydroxyergosta-7,22-diene, 7α,8α-epoxy-5α-ergost-22-ene-3β,5,6α-triol (major component), 3β,5α,6α,7α-tetrahydroxyergosta-8(14),22-diene, and 3β,5α,6α,7α-tetrahydroxyergosta-8(9),22-diene. The product obtained by M. Fieser et al. and identified as 3β,5α,6α-trihydroxyergosta-7,14,22-triene has been demonstrated to be constituted mainly of 3β,5α,6α-trihydroxyergosta-7,9(11),22-triene and 3β,5α,6α-trihydroxyergosta-7,22-diene, with 3β,5α,6α-trihydroxyergosta-7,14,22-triene as a minor component.
