9-(4-Chlorophenyl)-3,3,6,6-tetramethyl-1,2,3,4,5,6,7,8,9,10-decahydroacridine-1,8-dione

Abstract

In the mol­ecule of the title compound, C23H26ClNO2, the di­hydro­pyridine plane is approximately bisected by the plane of the orthogonal phenyl ring and the two fused rings are in the same boat main plane. A striking feature of the title compound is seen in the formation of a linear structure through N—H⋯O hydrogen bonds.

Green, three component highly efficient synthesis of 2-amino-5,6,7,8-tetrahydro-4-H-chromen-3-carbonitriles in water at ambient temperature

“…The conventional method for their synthesis involves the reaction of an ethanolic solution of arylidenemalono-nitrile with dimedone in the presence of piperidine at reflux for six hours (13). However, this method suffers from long reaction times and uses large quantities of organic solvents which may be harmful to the environment.…”
