K. Chinnakali et al., AN N-SUBSTITUTED 6,7-BENZOCOUMARIN-8,9-AZIRIDINE DERIVATIVE, Acta crystallographica. Section C, Crystal structure communications, 54, 1998, pp. 1299-1301
In the title compound, xahydropyrano[2',3':1,2]naphth[6;7]aziridin-2-o
ne, C21H18BrNO2, the tetrahydrobenzene ring adopts a flattened-boat co
nformation. The aziridine plane forms dihedral angles of 80.4(1) and 5
9.1(2)degrees with the tetrahydrobenzene and N-phenyl substituent ring
planes, respectively. The crystal structure is stabilized by weak C-H
... O intermolecular hydrogen bonds and pi-pi stacking interactions o
f the coumarin ring.
