- W2056571739 abstract "The optically active (+)-(20R)-de-AB-cholesta-8(14),22-dien-9-one (1) and (+)-(20S)-de-AB-isocholesta-8(14),22-dien-9-one (2) have been synthesised via stereo- and regio-selective Michael addition to the (3S)-methylcyclopentanone (4) derived from (S)-2,3-O-isopropylideneglyceraldehyde (5) and its (R)-isomer; the methyl group at C20 in (1) and (2) was introduced by Claisen rearrangement of the allyl vinyl ether (12) followed by decarbonylation of the resulting homoaldehydes (13) and (14), respectively." @default.
