Extended Tandem Reactions of 2H-1,2,3-Triazole N-Oxides with Dialkyl Acetylenedicarboxylates and N-Phenylmaleimide: Substituted Monocyclic 2,5-Dihydro-1,2,3-triazines and New Tetrahydrofuro-1,2,3-triazoles. Azolium 1,3-Dipoles Part 5.

The reaction of substituted 1,2,3-triazole 1-oxides with dialkyl acetylenedicarboxylate dipolarophiles gave a new route to monocyclic 1,2,3-triazine derivatives via a multi-step sequence of cycloaddition, sigmatropic rearrangements, and ring expansion.Wit
