2,5-Dihydro-1,2,3-triazine derivatives from attempted 1,3-dipolar cycloaddition of 1,2,3-triazole N-oxides with dimethyl acetylenedicarboxylate: a new ring expansion
Abstract
A new route to substituted 2,5-dihydro-1,2,3-triazine derivatives is described along with an X-ray crystal structure determination of one of these compounds.
