PREPARATION AND ABSOLUTE CONFIGURATION AT C(20) OF 21-NOR-5α-CHOLAN-24-->20-OLIDE DERIVATIVES

The lactones X and XI were obtained on reaction of the aldehyde III with lithium salt of methyl propynoate followed by hydrogenation of the intermediary esters IV and V.Treatment of the epoxides XXI and XXII with dilithium salt of acetic acid yielded the
