1,3-Dipolar Cycloadditions of 2-Ethoxy- and 2-(Ethylthio)-1-azetines with Nitrile Oxides, Nitrile Ylides and Nitrilimines: An Unexpected 1,2,4-Triazole Formation.

2-Ethoxy- and 2-(ethylthio)-1-azetines readily undergo 1,3-dipolar cycloadditions with nitrile oxides and nitrile ylides to give stable 4,5-bicyclic cycloadducts.With nitrilimines, however, the expected 1,3-dipolar cycloadducts and/or unexpected ring-open

REACTIONS OF HYDRAZIDIC HYDRAZINES WITH 1,3-DICARBONYL COMPOUNDS

The reactions of hydrazidic hydrazines (3) with acetylacetone, benzoylacetone, 3-methylacetylacetone, and ethyl acetylacetate were investigated.Basing on 1H and 13C NMR spectra, the structures of products were proposed.
