Abstract
1291148 Piperidyl steroids OSTERREICHISCHE STICKSTOFFWERKE AG 1 Oct 1970 [11 Oct 1969] 46829/70 Heading C2U Novel compounds of formula [wherein X-Y is C(α-H)-CH 2 , C(#-H)-CH 2 or C = CH and Z is a free or ketalized carbonyl group or an α- or #-hydroxymethylene or -acyloxymethylene group (where the acyl group is derived from an aliphatic, araliphatic or aromatic monocarboxylic acid), and wherein there may be a 4,5-double bond when Z is a free or ketalized carbonyl group and X-Y is saturated] are prepared by reduction with nascent hydrogen or with a complex aluminium hydride of compounds of formula which are in turn prepared by dehydrobromination with an organic or inorganic acid-splitting agent of compounds of formula which are in turn prepared by degradation with cyanogen bromide of the corresponding solanidane compounds. In the reduction of III to I, any 3-(free oxo) group must first be ketalized and may subsequently be regenerated. A 3- acyloxy group may be converted to a hydroxy group by the reduction.
