    Enantioselective syntheses of both (20R)- and (20S)-de-AB-cholesta-8(14), 22-dien-9-one (22 and 23), which are potential intermediates leading to vitamin D3, steroids and their analogues, have been developed. The (3R)-methyl-cyclopentanone 12 was obtained through a known procedure starting with (S)-2, 3-O-isopropylideneglyceraldehyde (8) or through inversion of the C6 position in compound 5 using the Mitsunobu reaction followed by orthoester Claisen rearrangement. The construction of the trans-angularly methylated CD ring was accomplished through stereo- and regioselective Michael addition of the lithium enolate of 12 to α-silylated vinyl ketone, followed by intramolecular aldol condensation.
