7-[(3,5-Di-tert-butyl-2-hydroxybenzylidene)amino]-4-methyl-2H-chromen-2-one
The title compound, C(25)H(29)NO(3), is a Schiff base derivative of coumarin 120. There are two structurally similar but crystallographically independent mol-ecules in the asymmetric unit. Both mol-ecules exist in E configurations with respect to the C=N double bonds. The dihedral angles between the coumarin and 3,5-di-tert-butyl-2-hy-droxy-benzyl-idene ring planes are 4.62 (7) and 14.62 (7)° f...
متن کامل7-(tert-Butyldiphenylsilyloxy)-2,2-dimethyl-1-benzofuran-3(2H)-one
The title compound, C(26)H(28)O(3)Si, is an allylic oxidation product of the tert-but-yl(2,2-dimethyl-2,3-dihydro-benzo-furan-7-yl-oxy)diphenyl-silane with N-bromo-succinimide and 2,2'-azobis-isobutyronitrile. The nine-atom bicyclic system is almost planar, with an r.m.s deviation of 0.0123 (2) Å and a maximum deviation of 0.031 (2) Å for the O atom. In the crystal, the mol-ecules pile up along...
متن کامل2,4-Bis(2-bromophenyl)-7-tert-pentyl-3-azabicyclo[3.3.1]nonan-9-one
The title compound, C(25)H(29)Br(2)NO, is a tert-pentyl analog of 2,4-bis-(2-bromo-phen-yl)-3-aza-bicyclo-[3.3.1]nonan-9-one [Par-thiban et al. (2008 ▶). Acta Cryst. E64, o2385]. Similar to its analog, the title compound exists in a twin-chair conformation with an equatorial orientation of the 2-bromo-phenyl groups. The benzene rings are inclined to each other at a dihedral angle of 29.6 (3)°. ...

The title compound, C25H29Cl2NO, which is a chloro analog of 2,4-bis-(2-bromo-phen-yl)-7-(tert-pent-yl)-3-aza-bicyclo-[3.3.1]nonan-9-one [Park, Ramkumar & Parthiban (2012). Acta Cryst. E68, o2946], exists in a twin-chair conformation with an equatorial orientation of the 2-chloro-phenyl groups. The tert-pentyl group on the cyclo-hexa-none adopts an exocyclic equatorial position and is disordere...

In the structure of the title compound, C(20)H(34)O(2)Si, a cis,trans,cis,cis-[4.5.5.5]fenestrane derivative, the geometry of the central C(C)(4) substructure shows considerable distortion from an ideal tetra-hedral arrangement towards planarity, with two opposite bridgehead bond angles of 128.87 (18) and 122.83 (17)°. The other bridgehead angle of the trans-bicyclo-[3.3.0]octane subunit is als...
