Abstract
Abstract 2-(2-Trimethylsilylethynylphenyl-X)-pyrimidines (2, X= O, S, NAc, CH2, CO) easily undergo intramolecular Diels-Alder reaction with inverse electron demand, to give tricyclic annelated pyridines in excellent yields. The synthesis of 2 and the cycloaddition reaction to give the tricyclic annelated pyridines is described.
