A new multicomponent catalytic approach to important fused imidazole bicyclic acetic esters, whose core is present in many biol. active principles, is presented. It is based on the sequential cyclization-alkoxycarbonylation-isomerization of readily available N-heterocyclic propargylamine derivatives, carried out under oxidative conditions using a simple catalytic system consisting of PdI2 (1 mol%) in conjunction with KI (1 equivalent), in the presence of AcONa as additive (1 equivalent) at 100°C under 20 bar of a 4 : 1 mixture CO-air. Under the optimized conditions, several N-(prop-2-yn-1-yl)pyridin-2-amines were smoothly converted into alkyl 2-(imidazo[1,2-a]pyridin-3-yl)acetates in fair yields (51-77%). The method was also applied to the conversion of N-(prop-2-yn-1-yl)pyrimidin-2-amine into 2-(imidazo[1,2-a]pyrimidin-3-yl)acetate and of N-(prop-2-yn-1-yl)pyrazin-2-amine into 2-(imidazo[1,2-a]pyrazin-3-yl)acetate. Some of the newly synthesized bicyclic derivatives have shown promising luminescence properties. The experimental part of the paper was very detailed, including the reaction process of 2,4,6-Trichloropyrimidine(cas: 3764-01-0Category: pyrimidines)
2,4,6-Trichloropyrimidine(cas: 3764-01-0) is a member of organic chlorides. Organic chlorides are compounds containing a carbon-chlorine bond, which are widely used in the oil field as a wax dissolver. They are generally not present in crude oils and are typically the result of additives, cleaning solutions or chemicals used for oil recovery.Category: pyrimidines
