摘要：

The axially chiral title compound was enantiomerically resolved by the diastercomer method via the camphorsultamamide of the corresponding dicarboxylic acid. The absolute stereochemistry of the (+)- and (-)-forms ([alpha](D) +32 and -33) was determined by X-ray analysis of one of the diastereomers of the sultamamide to be P and M, respectively, for the helicity about the C9-C9' bond. The observed CD and UV spectra were reasonably reproduced by the theoretical calculation based on the time-dependent density functional theory (TDDFT). The CD spectrum of the (M)-(-) form features a split curve around 270 nm assignable to the exciton coupling of the beta transition and a broad p band peak around 380 nm.
