Abstract
Synthesis of 19-hydroxylated analogues of androstenedione and testosterone carrying the cyclopropane ring in position 4β,5β is described. The starting allylic alcohol XIII was prepared by standard reactions from the epoxide I and transformed by Simmons-Smith methylenation to the cyclopropano derivative XXI. Hydrolyses and oxidations afforded the desired analogues XXIII and XXV.
