Title: Process for the manufacture of tertiary carbinols of the cyclopentano-polyhydrophenanthrene series
Filed: 1936-11-09
Abstract: The process described in the parent Specification in which cyclopentanopolyhydrophenanthrenes of the C18 and C19 series are reacted with metal organic compounds, to produce tertiary carbinols is modified in that unsaturated metal organic compounds are used. Suitable metal organic compounds mentioned are those produced for example from magnesium and the halides of acetylene and ethylene and their homologues and substitution products.  The cyclopentano - polyhydrophenanthrene compounds used are the same as are used in the parent Specification.  In cases where a free hydroxy group is present in the starting material, this is preferably protected by convertion into a group which on hydrolysis is easily reconverted into a hydroxyl group such as an ester or an ether group.  In examples: (1) acetylene is passed through an ether solution of magnesium and bromobenzene for 30 hours.  There is then added androstenolone acetate and in 3 days the reaction product is decomposed with ice water to give the acetate of ethinyl-17-androstendiol-3-17.  The compound may be purified by its silver salt; (2) acetylenedimagnesium - bromide is reacted in ether solution with androstenolone acetate and the product worked up as in example (1) to give the acetate of di-(3 : 17-dihydroxy)-androstenylacetylene; (3) androstenolone in ether is treated with coppered magnesium and reacted with vinyl bromide. On decomposition as before and extraction by means of its semicarbazide, there is obtained vinyl-17-androstendiol-3 : 17; (4) magnesium, bromobenzene and acetylene are reacted as in example (1) and there is then added with continuous passage of acetylene oestranol-3-one-17.  On working up ethinyl-17-oestrandiol-3 : 17 is obtained; (5) acetyl-androsterone is added to an ether solution of acetylenemonomagnesium bromide and the reaction product decomposed as before to give ethinyl-17-androstendiol-3 : 17-acetate-(3) which is isolated by means of its semicarbazone.
