Structural Investigations Of 1,2,3,4-Tetrahydrocarbazole Derivatives .1. 2,3-Dihydro-9-(Phenylsulfonyl)Carbazole-4(1H)-One And 1,2,3,4-Tetrahydro-Carbazole-1-Spiro-2'-[1,3]Dithiolane

Abstract

Rings A and B of the title compounds, C18H15NO3S (1) and C14H15NS2 (2), are planar while the hydrogenated C rings are not. The rings in the tetrahydrocarbazole skeleton are twisted with respect to each other.
