An enantioselective synthesis of tetrahydropyrrolo[1,2-c]pyrimidine-1,3-diones via a palladium-catalyzed intramolecular oxidative aminocarbonylation is described. The carbon-carbon double bond of alkenylurea substrates has been shown to react intramolecularly with a nitrogen nucleophile in the presence of a palladium catalyst under a carbon monoxide(More)
A Pd-mediated method for preparation of the strained macrocyclic moiety of complestatins is disclosed. Through stereoselective synthesis of model macrocycles and the S atropisomer of complestatin, the stereochemical identity of the anti-HIV agent complestatin is established. Investigations described herein illustrate that the compound previously reported as(More)
