Phytotoxic compounds produced by Fusarium equiseti. Part 10. The preparation and rearrangement of diacetylneosolaniol 9β,10β-epoxide

Abstract

Under conditions where trichothecodiol 9β,10β-epoxide rearranges to an 8α,9α : 10β,13-diepoxytrichothecan-12-ol, diacetylneosolaniol 9β,10β-epoxide gives a 9α,15 : 12,13-diepoxytrichothecan-10β-ol. Some by-products formed during the allylic bromination and allylic oxidation of diacetoxyscirpenol have been identified. One of them is a 3α,11α : 12,13-diepoxytrichothecene.
