(1R,4aS,10aR)-1,4a-Dimethyl-N-[(morpholin-4-yl)carbothio-yl]-7-(propan-2-yl)-1,2,3,4,4a,9,10,10a-octa-hydro-phenanthr
Abstract:
In the title compound, C(25)H(36)N(2)O(2)S, the cyclo-hexane and morpholine rings adopt chair conformations. The cyclo-hexene and cyclo-hexane rings form a trans ring junction with the two methyl groups in axial positions. The N-H and C=O bonds in the urea group are anti to each other. The crystal structure is stabilized by inter-molecular N-H⋯O hydrogen bonds.

Nomenclature of Aromatic Compounds with Multiple Substituents
For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...
