Abstract

Title cpds. having a double-bonded C5 and a gp. R1R2C=attached to C11 (R1 and R2 = H or 1-2C alkyl) are new, e.g. formula (I): (R3 = 1-4C alkyl; R4=H or OH, opt. esterfieid or etherified; R5 = O, alpha H, beta R6 or alpha R7, beta R6 where R6 = opt. esterified or etherified OH, R7 = opt. unsatd. 1-4C alkyl; X = 2H, O, or H, R8; R8 = opt. esterified or etherified OH). They have variously anabolic, androgenic, and ovulation- and gonad inhibiting activities and are esp. useful for fertility control. They are prepd. from the corresp. 11-3xo steroid by reaction with e.g. A3SiCR1 R2M (A, same or different, = alkyl or aryl; M = Mg halo or Li) and treating beta-silylcarbinol inter. with acid or alkali; A3P = CR1R2; a Grignard reaction or with Ph.S.CR1R2Li and redn. of inter. 11-hydroxy-11-phenylthioalkyl cpd.
