Abstract

The one-pot, two-step reactions of 4-picoline, a dialkyl acetylenedicarboxylate, and a 2-oxoindolin-3-ylidene derivative in 1,2-dimethoxyethane at elevated temperatures afford polyfunctionalized 2-[2-aryl-2-oxo-1-(2-oxoindolin-3-ylidene)ethyl]fumarates in moderate to good yields. The reaction mechanism involves the sequential formation of Huisgen’s 1,4-dipole, Michael addition, and loss of the pyridyl moiety.
