Cm. Moorhoff et al., New insights on the reaction of alkyl 3-oxo-4-(triphenylphosphoranylidene)butanoate and aldehydes under concentrated condensation conditions. One-potsynthesis of highly functionalised 6-oxocyclohex-4-ene-1,3-dicarboxylates, J CHEM R-S, (12), 1998, pp. 763-763A
A general method for the synthesis of substituted cyclohexenones 5 from the
condensation of acetoacetate phosphonium ylide 1 and saturated and unsatur
ated aldehydes 2, without activation, is described.
