Conjugate addition of lithiated (E)-but-2-enyldiphenylphosphine oxide (3) to 2-methylcyclopent-2-enone (2) in tetrahydrofuran at -20 deg C generates the enolate 8, which reacts rapidly with a series of β-sulfonyl vinyl ketones to generate unsaturated dike
Preparation of Hydrindenones from 2-Methylcyclopent-2-enone and the Carbanion of (E)-But-2-enyldiphenylphosphine Oxide: Efficient Enolate Trapping with β-Sulphonylvinyl Ketones
Haynes, Richard K.,Vonwiller, Simone C.
, p. 92 - 94 (2007/10/02)
The β-sulphonylvinyl ketones (5), (7), (9), and (10), easily prepared from β-(phenylthio)propionyl chloride or from methyl vinyl ketone, react efficiently with the enolate produced by the conjugate addition of the carbanion of (E)-but-2-enyldiphenylphosph
