Three-component reaction of arylsulfonamides, dialkyl acetylenedicarboxylates, and ethyl chlorooxoacetate promoted by triphenylphosphine and triethylamine provides a sufficient route for the synthesis of dialkyl N-(arylsulfonyl)-4-ethoxy-5-oxo-2,5-dihydro

Reaction of triphenylphosphine and an electron deficient acetylenic ester in the presence of strong N-H acid such as alkyl and aryl sulfamides or acetamide produces phosphorous ylides at room temperature in CH 2Cl2. The aryl sulfamide phosphoranes undergo a smooth transformation reaction in boiling toluene and produce iminophosphoranes. Springer-Verlag 2007.
