bisfunctional electrophile 16, with 1,3 dione 17 or arylnitromethane derivative 7, led to adducts 18 and 20 respectively, through a sequential process involving η3-allylpalladium alkylation-Michael addition. Nitro ester 20 constitutes useful potential precursor for the synthesis of Erythrina alkaloids.
