Triazolophthalide has been synthesized in a seven step sequence from phthalide in 24percent overall yield, and triazolodihydrocoumarin has been prepared in nine steps from dihydrocoumarin in 20percent overall yield.The 1H and 13C nmr spectra and the tautomeric equilibria of the final compounds and intermediates are discussed.
