Description
Summary: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.
