چکیده
In the title compound, C(19)H(11)NO(3), the isoindolinone ring system is approximately planar with a maximum atomic deviation of 0.071 (1) Å and the five-membered ring of the dihydro-benzo[g]indol-3-one unit assumes an envelope conformation. The naphthalene ring system makes a dihedral angle of 39.47 (4)° with the mean plane of the isoindolinone system. Inter-molecular O-H⋯O and C-H⋯O hydrogen bonding helps to stabilize the crystal structure.

The title chiral compound, C(13)H(14)N(2)O(4), was prepared by an intra-cyclization reaction of methyl (S)-1-(4-hydr-oxy-5-meth-oxy-2-nitro-benz-yl)-5-oxopyrrolidine-2-carboxyl-ate in the presence of ethanol and iron. The five-membered substituted pyrrole ring adopts an approximate envelope conformation, while the seven-membered substituted diazepine ring displays a twist-boat conformation. Int...
متن کاملChemical shift assignments of two oleanane triterpenes from Euonymus hederaceus.
(1)H-NMR and (13)C-NMR assignments of 12-oleanene-3,11-dione (compound 1) were completely described for the first time through conventional 1D NMR and 2D shift-correlated NMR experiments using (1)H-(1)HCOSY, HMQC, HMBC techniques. Based on its NMR data, the assignments of 28-hydroxyolean-12-ene-3,11-dione (compound 2) were partially revised.
