Diethyl (N-methoxy-N-methylcarbamoylmethyl)phosphonate (1) is easily prepared by heating 2-chloro-N-methoxy-N-methylethanamide and triethylphosphite. Reagent 1 is useful for converting aldehydes and ketones into compounds containing an alpha,beta-unsaturated N-methoxy-N-methylamide group with high E selectivity.

The two carbon homologation of carbonylcompounds to α,β-unsaturated aldehydes is achieved by the Wittig-Horner reaction with N-methoxy N-methyl diethylphosphonoacetamide followed by lithiumaluminumhydridereduction.

A new synthetic method of N-methoxy-N-methylamides is developed. The palladium-catalyzedcouplingreaction of N-methoxy-N-methylcarbamoyl chloride furnished N-methoxy-N-methylamide in moderate to good yield, wherein a carbonyl equivalent was appended to sp and sp2 carbon atoms as a versatile synthetic basis for further manipulation.
