Description |
809-815
The cycloaddition reaction of ethyl 2-(azidomethyl)-4H-chromene-3-carboxylates with phenylacetylene/ 4-fluorophenylacetylene have provided a mixture of 2H- and 4H-triazolylchromene-3-carboxylates. 4-Methoxyphenylacetylene, 3-methylphenylacetylene and acetylenedicarboxylates have provided exclusively 2H-triazolylchromene-3-carboxylates. Interestingly, prop-2-yn-1-ol and ethyl propiolate have provided exclusively 4H-triazolylchromene-3-carboxylates. |
