Novel (3+2) dipolar cycloadditions of pyridinium ylides [PDF]

, 2017
This thesis describes advances in novel (3+2) dipolar cycloadditions of pyridinium ylides, their reactions with electrophilic alkenes afford tetrahydroindolizines which can possess alkaloid-like scaffolds.

Studies on Heterocyclic Compounds. XIV. 1, 3-Dipolar Cycloaddition Reaction of Dimethyl Acetylenedicarboxylate with Phenylhydrazones

Chemical and Pharmaceutical Bulletin, 1973
1, 3-Dipolar cycloaddition of aldehyde hydrazones with dimethyl acetylenedicarboxylate without solvent gives rise to dimethyl 1, 3-diphenylpyrazole-4, 5-dicarboxylate, and in some cases trimethyl 1-phenylpyrazole-3, 4, 5-tricarboxylate as a by-product.

Transition metal complexation in 1,3-dipolar cycloadditions

, 2003
Transition metal complexation of organic molecules is becoming common in the field of 1,3-dipolar cycloadditions as a successful methodology to increase reactivities and to control selectivities. The literature data on this subject are here reviewed in a
