ASYMMETRIC DIELS-ALDER REACTION OF A CHIRAL ALLENIC ESTER: ENANTIOSELECTIVE SYNTHESIS OF (-)-β-SANTALENE

Article abstract of DOI:10.1016/S0040-4039(00)86221-8

The Lewis-acid promoted Diels-Alder reaction of the allenic ester 10 provides the adduct 11 with excellent ?-facial selection leading to an efficient enantioselective synthesis of (-)-β-santalene and to the recovery of the chiral control element 7.
