Title: 6ª‰:19-oxido-steroids and their oxidation products and process for their manufacture
IPC: C07J1/00
Filed: 1961-07-17
Abstract: The invention comprises (1) a process for the preparation of a 6b ,19-oxido-steroid or the lactone of a 6b -hydroxy-steroid-19-acid, wherein a 19-unsubstituted 6b -hydroxy-steroid is treated in a non-polar solvent with a compound capable of liberating monovalent positive chlorine, bromine or iodine, and, when the lactone is required, the oxido-steroid is oxidized with ruthenium tetroxide or chromic acid or an oxidizing derivative thereof; (2) 6b ,19-oxido-steroids; and (3) the 19,6b -lactones of 6b -hydroxy-steroid-19-acids containing a 5a -halogen atom, a 5-hydroxy group or D 4-3-oxo grouping. The process may be applied to steroids of the androstane, pregnane, cholane, cholestane, stigmastane, spirostane and cardanolide series which may contain free ketalized or enolized oxo groups, esterified or etherified hydroxyl groups, alkyl groups, halogen atoms, oxido or lactone groups or double bonds in one or more positions in the ring-system or 17-side chain. Suitable halogen-containing reagents are N-halo-amides and -imides, cyanogen halides, alkyl or acyl hypohalites, iodine and iodine halides. Acyloxy groups in the products may be hydrolysed before or after the oxidation process, and resulting hydroxy groups oxidized to keto groups.  D 4-double bonds may be introduced by bromination and dehydrobromination, or 5a -(hydroxy or halogen)-3-ketones may be treated with alkaline agents or acid to give D 4-3-ketones. 17-Oxo-androstane products may be converted to the corresponding 17b -hydroxy-17a -hydrocarbon-compounds with metal-hydrocarbon reagents, or they may be reduced to the 17b -hydroxy compounds, with or without concomitant reduction of a 3-keto group which, if it is reduced, may then be re-oxidized. 17a - and/or 21-hydroxyl groups may be introduced into 20-keto pregnanes by conventional methods, and hydroxyl groups may be esterified. Spirostanes may be degraded via furostenes to D 16-20-oxo-pregnens.  Many detailed examples illustrate the processes of the invention and these optional processes.  5a  - chloro - 6b  - hydroxy - steroid starting materials are prepared from the corresponding D 5-steroids and hypochlorous acid.  The cyclic 3a ,5a -carbonate of 3a ,5a ,6b -trihydroxy - 20 - oxo - pregnane is prepared from the triol and phosgene.  The 18,20-lactone of D 5-3b  - acetoxy - 20b  - hydroxy - pregnene - 18 - acid is prepared by treating D 5-3b -acetoxy-20b -hydroxy-pregnen with lead tetraacetate and iodine and oxidizing the product.  3b ,17a - diacetoxy - 6 - oxo - androstane is a by-product in the treatment of 3b ,17a -diacetoxy - 6b  - hydroxy - androstane with mercuric or silver acetate and iodine.
