(±)-Ethyl 6,7-dimethoxy-1-(1H-pyrrol-2-yl)-1,2,3,4-tetrahydroisoquinoline-2-carboxylate

Abstract

Key indicators: single-crystal X-ray study; T = 290 K; mean (C-C) = 0.005 Å; R factor = 0.065; wR factor = 0.157; data-to-parameter ratio = 15.0.In the title compound, C 18 H 22 N 2 O 4 , the dihedral angle between the pyrrolyl and quinolinyl fragments is 68.97 (2) . Two non-classical intramolecular C-HÁ Á ÁO hydrogen bonds stabilize the molecular geometry. In the crystal structure, molecules form infinite chains via moderate intermolecular N-HÁ Á ÁO(CH 3 ) hydrogen bonds. Related literature ExperimentalCrystal data
