title: Asymmetric total synthesis of batzelladine D.
abstract: [formula: see text] The first enantioselective total synthesis of a batzelladine alkaloid is described. The central reaction in the synthesis of (-)-batzelladine D (2) is a tethered Biginelli condensation of a guanidine aldehyde and an acetoacetic ester to generate a 7-substituted-1-iminohexahydropyrrolo-[1,2-c]pyrimidine intermediate having the anti stereochemistry of the methine hydrogens flanking the pyrrolidine nitrogen.
