Abstract
1,240,698. Halo-zinc-methylene reagent; preparation of methylene steroids. G. D. SEARLE & CO. 16 Oct., 1968 [17 Oct., 1967], No. 49081/68. Headings C2J and C2U. A process for the manufacture of a halozinc methylene reagent comprises contacting a zinclead couple with a methylene halide in tetrahydrofuran or an alkylene glycol ether or dialkoxy ether at elevated temperature. Preferably CH 2 Br 2 or CH 2 I 2 and T.H.F. are used. A typical iodozinc methylene tetrahydrofuran reagent crystallized from solution contains 15-25% by weight Zn, 50-65% by weight I and 13-20% by weight C. The reagent may be used to react with a reactive steroidal ketone to produce a methylene steroid. Steroid derivatives which may be used include those of the pregnane, estrane and androstane series. The ketone may be activated by an adjacent hydroxy, acyloxy or oximino function. The ketone group may be in the 3-, 20- or 6-positions. It is stated that 6-methyleneandrostane - 3(#,5α,17# - triol, which may be made from the corresponding 3,17-diacetate formed by this method, may be reacted with CrO 3 to yield the 3,17-dione, hydrogenated using a platinum catalyst to yield the 6α-methyl derivative, and dehydrated with SOCl 2 to yield 6α - methyl androst - 4 - ene - 3,17 - dione, which may then be reduced with NaBH 4 to yield 17#- hydroxy - 6α - methyl androst - 4 - en - 3 - one, a compound having both anabolic and androgenic properties. A number of other methylenesteroid products are also described, and the conversion of 3# - benzyloxy - 5α - hydroxy-6- methylenepregnan - 20 - one 20 - ethylene ketal to the free 20-one, the formation of 6-methylenandrostane - 3#,5α,l7# - triol triacetate from the 3,17-diacetate and the formation of the corresponding tripropionate from the dipropionate.
