1,3-dipolar cycloaddition reactions of some azomethine imines and azomethine ylides

open access: yes, 2005
In this work, 1,3-dipolar cycloaddition reactions of three azomethine imines(betaines) and, three azomethine ylides, which are the new in the literature, to thedifferent dipolarophiles such as; dimethyl acetylene dicarboxylate, diethylacetylenedicarboxylate, vinyl acetate, diphenyl acetylene, phenylacetylene andvinylene carbonate are described.
