Synthesis of allenes by double Horner-Wadsworth-Emmons reaction

LDA treatment of aldehydes or ketone with alkenylphosphonates 2, prepared by Horner-Wadsworth-Emmons (HWE) reaction of methylenebisphosphonate 1 with aldehydes, afforded Baylis-Hillman reaction-type products 5 in high yields. HWE olefination of 5 with KH or KH-18-crown-6 as a base provided allenes in good yields. One-flask procedure was successfully developed starting from 1 to afford an allene in a reasonably good yield.

STUDIES ON ORGANOPHOSPHORUS COMPOUNDS XLV. STRUCTURAL EFFECTS OF ESTER ALKYL GROUP OF DIALKYL ALLYLPHOSPHONATE CARBANION ON THE REGIOSELECTIVITY OF ELECTROPHILIC ADDITION

The steric effect of the ester alkyl group of dialkyl allylphosphonate carbanion on the regioselectivity of the reaction with benzaldehyde was investigated.The steric contribution was evaluated by substituent parameter and molecular mechanics calculation.
