title: Self-condensation of N-tert-butanesulfinyl aldimines: application to the rapid asymmetric synthesis of biologically important amine-containing compounds.
abstract: [reaction: see text] Highly diastereoselective intra- and intermolecular self-condensation reactions of N-tert-butanesulfinyl aldimines have been developed and applied to the rapid, asymmetric synthesis of trans-2-aminocyclopentanecarboxylic acid and the drug candidate SC-53116. Key to both syntheses is a novel microwave-assisted reaction in which N-sulfinyl aldimines are cleanly converted into nitriles in high-yielding concerted elimination processes.
