Use of dimethyldioxirane in the preparation of highly reactive compounds: First direct epoxidation of precocenes

Natural precocenes and related analogues react with dimethyldioxirane to give the corresponding 3,4-epoxy derivatives in very high yields. This procedure constitutes the first direct preparation of these highly reactive compounds.

The Synthesis of the Epoxide and some other possible Metabolites of Precocene I

The synthesis of precocene I epoxide, 3,4-epoxy-7-methoxy-2,2-dimethylchroman (8), is described.This compound is the highly reactive metabolite responsible for the biological effects of the precocenes.The syntheses of some other oxygenated derivatives of precocene I, which are themselves possible metabolites, are also described.
