Synthesis and Configuration of Natural Dracaenones

Several dracaenones were synthesized in enantiopure forms for the first time. The key chiral center at C-7 was installed with well-defined stereochemistry using either an Evans aldol condensation or a chiral oxidant-mediated asymmetric epoxidation, while

Modified chiral triazolium salts for enantioselective benzoin cyclization of enolizable keto-aldehydes: Synthesis of (+)-sappanone B

Equation Presented Asymmetric synthesis of (+)-sappanone B (1), a natural product with a 3-hydroxy chromanone structure, was achieved via enantioselective benzoin cyclization by using a modified Rovis catalyst and triethylamine. This catalyst enabled the

Homoisoflavonoids and Related Compounds. IV. Absolute Configurations of Homoisoflavonoids from Caesalpinia sappan L.

The absolute configuration of the homoisoflavonoidal components, 4-O-methylsappanol, 4-O-methylepisappanol, sappanone B, 3-deoxysappanone B and 3'-deoxysappanone B, from Caesalpinia sappan L. were determined on the basis of chemical transformations and the optical properties.Keywords - Caesalpinia sappan; Leguminosae; Sappan Lignum; heartwood; homoisoflavonoid; absolute configuration
