A simple and efficient approach has been developed for the preparation of coumarin natural products such as dihydroxanthyletin, xanthyletin, decursinol and marmesin starting from commercially available 2,4-dihydroxybenzaldehyde with very good yields. Wittig homologation and Claisen rearrangement are the protocols used to achieve these molecules.

Coumarins are ubiquitous in higher plants and exhibit various biological actions. The aim of this study was to investigate the structure-activity relationships of coumarin derivatives on tert-butyl hydroperoxide (t-BHP)-induced oxidative damage in human hepatoma HepG2 cells. A series of coumarin derivatives were prepared and assessed for their cytoprotective effects. Among these, a caffeoyl acid-conjugated dihydropyranocoumarin derivative, caffeoyllomatin, efficiently protected against cell damage elicited by t-BHP. Our findings suggest that caffeoyllomatin appears to be a potent cytoprotective agent.

Four novel furanocoumarin glucosides, candinosides A, B, C and D (1-4), were isolated from the roots of Heracleum candicans Wall. Their structures were established using chemical and spectral methods.
