Abstract
Palladium catalyzed condensation of bisfunctional electrophile 16, wit h 1,3 dione 17 or arylnitromethane derivative 7, led to adducts 18 and 20 respectively, through a sequential process involving eta 3-allylpa lladium alkylation-Michael addition. Nitro ester 20 constitutes useful potential precursor for the synthesis of Erythrina alkaloids. (C) 199 8 Elsevier Science Ltd. All rights reserved.
