Abstract
1,231,472. 1 – Azidomethyl – 2 – oxa – steroids. CIBA GEIGY A.G. 21 May, 1968 [24 May. 1967], No. 24178/68. Headings C2C and C2U, Novel 1 – azidomethyl – 3 – oxo – 2 – oxasteroids of the 5α- or 5#-androstane series which contain in the 17-position a free or functionally converted hydroxyl or oxo group are prepared by treatment with metal azides of reactive esters of the corresponding 1-hydroxymethyl compounds. Suitable reactive esters are the 1-halomethyl and 1-aliphatic- or -aryl-sulphonyloxymethyl compounds. In the products a functionally converted hydroxyl or oxo group may be liberated or a free hydroxy or oxo group functionally converted, e.g. esterified, etherified or ketalized. 1# – Mesyloxymethyl – 3 – oxo – 17# – acetoxy- 2-oxa-5α,-androstane is prepared by hydroxylating #
