Synthesis of 7-(2-R-pyrimidin-4-yl)- and 7-(2-R-[1,2,4]triazolo[1,5-a]pyrimidin-7-yl)-2,2,4,6-tetramethyl-1,2,3,4-tetrahydroquinolines

Abstract

Cyclization of 3-(dimethylamino)-1-(2,2,4,6-tetramethyl-1,2,3,4-tetrahydroquinolin-7-yl)prop-2-en-1-one with carboximidamides, guanidines, and 1,2,4-triazol-5-amines afforded a number of new 2,2,4,6-tetramethyl-7-(2-R-pyrimidin-4-yl)-1,2,3,4-tetrahydroquinolines and 2,2,4,6-tetramethyl-7-(2-R-[1,2,4]triazolo-[1,5-a]pyrimidin-7-yl)-1,2,3,4-tetrahydroquinolines.
