Microwave-Assisted [3 + 2] Cycloadditions of Azomethine Ylides

, 2016
The microwave-assisted intramolecular [3 + 2] cycloaddition reaction of azomethine ylides to activated and nonactivated alkenes and alkynes is described. The procedure allows the synthesis of pyrrolidines and pyrrole products in good to excellent overall

Utilizing MEDT analysis of [3 + 2] cycloaddition reaction: x-ray crystallography of spirooxindole linked with thiophene/furan heterocycles and triazole framework

BMC Chemistry
Hybridization of spirooxindole with different pharmacophores such as triazole and heterocycle such as thiophene and furan moiety was achieved by the [3 + 2] cycloaddition (32CA) reaction approach. Structural investigations of the compounds 4a and 4b were

An investigation of the scope of the 1,7-electrocyclization of α,β:γ,δ-conjugated azomethine ylides

, 2014
Substituents on the diene component have little influence on the periselectivity of the cyclizations of alpha,beta:gamma,delta-conjugated azomethine ylides, with 1,7-electrocyclizations predominating.
