Abstract:
The three-component reaction of triphenylphosphine, dimethyl acetylenedicarboxylate and 3-arylamino-1-methyl-1H-pyrrole-2,5-diones in CH2Cl2 at room temperature resulted in functionalized 3-(triphenyl-λ5-phosphanylidene)succinates in nearly quantitative yields. However, tri(n-butyl)phosphine promoted reaction of dialkyl acetylenedicarboxylates and 3-arylamino-1-methyl-1H-pyrrole-2,5-diones in CH2Cl2 afforded functionalized pyrrolo[3,4-b]pyridine-4-carboxylates in satisfactory yields.

Reaction between triphenylphosphine, dimethy acetylenedicarboxylate and amines produces phosphorus ylids which undergo a smooth reaction with ethyl chlorooxoacetate and triethylamine to produce dimethyl N-aryl-(or alkyl)-4-ethoxy-5-oxo-2,5-dihydro-1 H-pyrole-2,3-dicarboxylates in high yields.

Abstract:
Protonation of the reactive intermediate produced from the reaction between trialkyl phosphites and dimethyl acetylenedicarboxylate by ethyl carbazones of aromatic aldehydes following by conjugate addition of the anion of ethyl carbazone on the phosphonium salt intermediate leads to functionalised phosphonates in good yields. Triphenylphosphine also reacted with dimethyl acetylenedicarboxylate and ethyl carbazones to produce functionalised phosphoranes in good yields.

Abstract:
The bromination of dimethyl acetylenedicarboxylate initially results in mostly trans dimethyl 2,3-dibromofumarate, which then converts into the more stable cis isomer. The trans-to-cis conversion is spontaneous and greatly accelerated by light.

Abstract:
Reactions of 5-cyano-1,4-diphenylpyridazino[4,5-a]indolizines with dimethyl acetylenedicarboxylate afforded the 1:2 adducts regioselectively and, unexpectedly, in a Michael fashion rather than in a 1,3-dipolar manner. The structure of the products was established by X-ray crystallography. Regiospecific formation of the observed product 3 can be explained by the higher nucleophilicity of the nitrogen at the 2 position than at the 3 position of the 5-cyano-1,4-diphenylpyridazino[4,5-a]indolizine 1 owing to the contribution of a resonance structure 5 to the hybrid.

AbstractThis chapter is a complete revision and update of the earlier Science of Synthesis contribution from 2000 describing methods for the synthesis of phosphorus analogues of indolizines. The previous route to this rare ring system, reaction of a phosphole with dimethyl acetylenedicarboxylate, has now been joined by a metathesis-based method leading to the parent dibenzophosphindolizine and its chalcogen derivatives.

Abstract:
The cycloaddition reactions represent an important way to obtain cyclic structures and take place between two or more reactants containing double or triple bonds in the molecule. After Huisgen, the addition of 1,3-dipole to a dipolarophile, takes place through a concerted mechanism, when two  bonds are formed. [1,2] The purpose of this research is to study the Huisgen [3+2] dipolar cycloaddition reactions carried out in a conventional way (stirring at room temperature) and non-conventional way (ultrasonic irradiation), between benzimidazolium-ylides and an activated symmetric substituted alky
