title: Synthesis of the ABC Tricyclic System of Daphnicyclidin A.
abstract: A substrate-stereocontrolled synthesis of the ABC tricyclic system of daphnicyclidin A is developed. The key reactions include an efficient tandem N-allylation-SN2' reaction to assemble 2,3,4-cis trisubstituent pyrrolidine ring C and two intramolecular Horner-Wadsworth-Emmons reactions to construct cycloheptanone ring A and piperidine ring B.
