STEROIDS IV IODOKETONES A METHOD FOR THE CONVERSION OF ALL OSTEROIDSINTOI 4 3 KETOSTEROIDS

Abstract

2-Bromo-3-ketoallosteroids, in contrast to 4-bromo-3-keto;;teroids of the normal series, react readily with sodium iodide in acetone solution to afford the corresponding 2-iodo ketones. When refluxed with γ-collidine, deiodination occurs and the saturate
