(Z)-2-(1-Phenylsulfonyl-1H-indol-3-ylmethylene)-1-azabicyclo[2.2.2]octan-3-one and (Z)-(S)-2-(1-phenylsulfonyl-1H-indol-3-ylmethylene)-1-azabicyclo[2.2.2]octan-3-ol
摘要:
The title compounds, C22H20N2O3S, ( I), and C22H22N2O3S, (II), crystallize in space groups P(1) over bar and P2(1)2(1)2(1), respectively. The indole rings are planar and the benzene ring of the phenylsulfonyl group makes a dihedral angle with the mean plane of the indole ring of 90.2 (2)degrees in (I) and 94.0 (2)degrees in (II). In both molecules, the double bond connecting the azabicyclic and indole moieties has a Z geometry. Compound (II) was obtained as an enantiomerically pure crystal and has the 3S configuration.

In crystals of the title compound, C23H23N5O3S, the indole system is planar and the phenyl ring of the phenylsulfonyl group makes a dihedral angle with the best plane of the indole system of 77.18 (4)degrees. The olefinic bond connecting the azabicyclic and indole systems has Z geometry. The geometry adopted by the C = O bond with respect to the N-N bond is trans. The O atom of the carbonyl group of each molecule is hydrogen bonded to the hydrazidic H atom of an adjacent molecule to form an eight-membered-ring dimeric structure.
