Phosphorus ylides have been prepared in excellent yields by the three-component reaction of activated electron-deficient acetylenic esters (dimethyl and diethyl acetylenedicarboxylate) and thiourea derivatives in the presence of triphenylphosphine. In some cases, these ylides were cyclized to dihydropyrimidothiazine, thioxoimidazolidine, and thioxotetrahydropyrimidine derivatives.
