New Rearrangements in the Pregnane Side Chain

Reaction of 17-acetoxy-21-(acetylthio)-4-pregnene-3,20-dione (3) with a large excess of sodium azide in methanol yields a mixture of rearrangement products consisting of the methyl etianate 11 and the spirodithiolanone 12.The influence of temperature and solvent on the progress of the reaction has been studied.In order to obtain further informations pertaining to the mechanism of rearrangement, the compounds 4-10, the 6α-methyl and the D-homo substances 13b and 13d have been synthesized and subjected to the conditions of rearrangement.
