Synthesis of the naturally occurring prenylated coumarins balsamiferone and cedrelopsin by domino reactions

Regioselective one step synthesis of naturally occurring prenyl coumarin balsamiferone is described using domino Wittig reaction, 3,3-sigmatropic rearrangements and deprenylation, while regioselective synthesis of cedrelopsin is described via domino Witti

Cascade wittig reaction-double claisen and cope rearrangements: One-pot synthesis of diprenylated coumarins gravelliferone, balsamiferone, and 6,8-diprenylumbelliferone

A cascade Wittig reaction-double Claisen and Cope rearrangements has been employed for a one-pot synthesis of diprenylated coumarins gravelliferone, balsamiferone, and 6,8-diprenylumbelliferone from a common precursor 2,4-diprenyloxybenzaldehyde.

Tandem Thermal Claisen-Cope Rearrangements of Coumarate Derivatives. Total Syntheses of the Naturally Occuring Coumarins: Suberosin, Demethylsuberosin, Ostrithin, Balsamiferone and Gravelliferone

Thermal Claisen rearrangements of derivatives of 4'-O-methyl and 4'-O-benzyl methyl coumarates 3, prepared from the corresponding umbelliferone derivatives, have been investigated.Simple allyl derivatives rearrange predominantly to the vacant ortho-positi

An Iterative Procedure for the Synthesis of the Diprenylated Coumarins Balsamiferone and Gravelliferone from Umbelliferone via Multiple Sigmatropic Rearrangements

Repeated sequences of sigmatropic rearrangements initiated by a Claisen rearrangement permit the synthesis of the 3,6-disubstituted umbelliferone derivatives balsamiferone (4) and gravelliferone (6) from umbelliferone.
