✦ Synopsis

Syntheses of bile acid cyclooligomers with 12-and 7,12-oxo groups (6a؊d, 7a؊c, 8a؊b) by the Yamaguchi method are described. Cyclotrimerization is the principal reaction route for these cholic acid systems. Conversion of 7-and 12-hydroxy groups in cholic acid (1a؊b) to oxo groups (4a؊c,

Stereoselective synthesis of 12-oxo-PDA starting with (1R,3S)-cyclopenten-1,3-diol monoacetate is accomplished. Key transformations are copper-catalyzed installation of the C(1)-C(8) chain onto the cyclopentene ring and construction of the C(14)-C(18) chain. Similarly, 13-epi-12-oxo-PDA was synthesi

In the title compound, C 22 H 15 NO 3 , the quinoline system is essentially planar, and the mean plane of the indenone ring system is almost coplanar with the quinoline group. The crystal structure is stabilized by inter-and intramolecular C-HÁ Á ÁO hydrogen-bonding interactions.
