  • Title: Diastereoselective cationic tandem cyclizations to N-heterocyclic scaffolds: total synthesis of (-)-dysibetaine PP.
    Author: Ijzendoorn DR, Botman PN, Blaauw RH.
    Journal: Org Lett; 2006 Jan 19; 8(2):239-42. PubMed ID: 16408884.
    Abstract:
    [reaction: see text] Herein, we report a short and diastereoselective synthesis of the natural product (-)-dysibetaine PP. The key step in the synthetic sequence is a novel highly diastereoselective tandem-cyclization reaction of an enantiomerically pure dipeptide. This cyclization methodology is applied in the synthesis of a broader range of N-heterocyclic scaffolds.
