Diastereoselective synthesis of (±)-heliotropamide by a one-pot, four-component reaction

J Org Chem. 2010 Dec 3;75(23):8333-6. doi: 10.1021/jo1019317. Epub 2010 Nov 9.

Abstract

The first synthesis of heliotropamide is reported. The preparation of this 2-oxopyrrolidine (γ-lactam) natural product relied on a diastereoselective one-pot, four-component reaction (4CR) for the assembly of the core structure. On the basis of chemical shift correlation and NOESY experiments, the previously unknown alkene geometry of heliotropamide is assigned as E.
