Steroids and related studies. Part XIX. Products of the Schmidt reaction with cholest-4-ene-3,6-dione
Abstract
Treatment of cholest-4-ene-3,6-dione with an equimolar quantity of sodium azide in polyphosphoric acid yields 4-aza-A-homocholest-4a-ene-3,6-dione and 3-aza-A-homocholest-4a-ene-4,6-dione. The product obtained on treating 4-aza-A-homocholest-4a-ene-3,6-dione with 1 mol. equiv. of sodium azide or cholest-4-ene-3,6-dione with 2 mol. equiv. of sodium azide has been shown to be 4,6-diaza-AB-dihomocholest-4a-ene-3,7-dione.
