Synthesis of (±)-licarin B and eupomatenoids-1 and -12: A general approach to 2-aryl-7-alkoxy-benzofuranoid neolignans

New synthesis of the title compounds are described using Lewis acid-promoted reactions of styrenes with N-phenylsulfonyl-1,4-benzoquinone monoimines to regioselectively form the 2-arylbenzofuranoid ring system followed by conversion of the aromatic N-phenylsulfonyl moiety into a propenyl substituent.

Natural Benzofuranes. Synthesis of Eupomatenoids-1, -3, -4, -5, -6, -7, and -13

A group of eupomatenoids, natural lignans possessing 2-aryl-3-methyl-5-propenylbenzofuran structures have been synthesized by short pathways which include the intramolecular Wittig reaction of an o-bromoethylaryl benzoate ester as a key step.
