Abstract:
In this patent application a suitable hydroxy-1,2,3,4-tetrahydroquinoline either 7-hydroxy or 5-hydroxy is reacted with ethyl-4,4,4-trifluoroacetoacetate to produce either 2-keto-4-trifluoromethyl-6,7,8,9-tetrahydro-2H-pyrano 3,2-g-quinoline if 7-hydroxy-1,2,3,4-tetrahydroquinoline is the reactant or 2-keto-4-trifluoromethyl-7,8,9,10-tetrahydro-2H-pyrano 3,2-f-quinoline if 5-hydroxy-1,2,3,4-tetrahydroquinoline is the reactant. Also, m-aminophenol is reacted with ethyl-4,4,4-trifluoro-acetoacetate to produce 7-amino-4-trifluoromethyl coumarin. The compounds produced are useful as laser dyes.
