Synthesis of 16α,17α-epoxy-20-isoxazolylsteroids was carried out starting with dehydropregnenolone acetate. Transformation procedures for preparation therefrom of open-chain compounds were considered. Physico-chemical characteristics of compounds synthesized were investigated.

Abstract1,3-Dipolar cycloaddition of nitrile oxides to 17β-hydroxy-17α-vinyl steroids of the estrone series proceeds both regio- and stereoselectively. The stereoselectivity of the process decreases in going to steroids of the androstane series. The major epimer has S configuration of the new chiral center.
