摘要:
A synthesis of a Precursor 2 for the Elisabethin A skeleton is reported. Containing a masked quinone and a (E,Z)-diene subunit, it has the required elements for the envisaged intramolecular Diels-Alder reaction to form the tricyclic system of Elisabethin A. Starting from methylresorcinol, the sequence involves the preparation of an arylacetic acid, which was a-alkylated by a chiral building block. Subsequent HWE reaction and cis-selective Wittig olefination furnished the diene with the desired leometry.
