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.

Abstract:
The azomethine ylide generated from the reaction of a corrole-3-carbaldehyde and N-methylglycine was trapped with dimethyl fumarate, dimethyl acetylenedicarboxylate and fullerene C60 in 1,3-dipolar cycloadditions. A similar azomethine ylide generated from a corrole-2-carbaldehyde was trapped with 1,4-naphthoquinone, yielding the expected dehydrogenated 1,3-dipolar cycloadduct and a quinone-fused corrole derivative. A detailed synchrotron single-crystal X-ray diffraction analysis of the gallium(III)(pyridine) complex of 5,10,15-tris(pentafluorophenyl)corrole-3-carbaldehyde is also presented.

Abstract:
Azomethine ylides generated from 5-(alkoxycarbonylmethyl) phenanthridinium cations I were used in the 1,3-dipolar cycloadditions with dimethyl acetylenedicarboxylate as dipolarophile. The cycloadducts II were found to be very unstable species and readily oxidized to fully aromatic pyrrolo[1,2-f]phenanthridines III. Their structure was compared with the compounds formed by the oxidation of cycloadducts IV of the same ylide with dimethyl fumarate and maleate. In both cases pyrrolines V were found as intermediates. The structure of the products was determined by NMR and MS as well as by X-ray ana

Abstract:
A new method of synthesis of 3-substituted thieno[3,2-b][1]benzothiophenes based on a halogen dance process was developed. The cycloaddition reaction of the title compound with dimethyl acetylenedicarboxylate leads to the formation of a complex mixture of products resulting from a series of consecutive reactions of the primary adduct.

It has been shown that a second addition to this system occurs only with singlet oxygen and with benzyne. Furthermore, it has been established that the second addition is retarded because of the strain in the cycloheptatriene molecule. The anti b

AbstractThree benzoindolizine derivatives, 1, 2, and 3, were obtained via 1,3-dipolar cycloaddition. The reaction of 1-(2′-benzimidazolylmethyl)isoquinolinium ylides with dimethyl acetylenedicarboxylate gave a mixture of pyrrolo[2,1-a]isoquinoline-1,2-dicarboxylate (1) and 1,10b-dihydropyrrolo[2,1-a]isoquinoline-1,2-dicarboxylate (2) derivatives containing a benzimidazole moiety. The reaction of this isoquinolinium N-ylide with dimethyl maleate gave an unexpected 2,3-dihydropyrrolo[2,1-a]isoquinoline-1,2-dicarboxylate (3).
