Title: Stereoselective synthesis of E,Z-configured 1,3-dienes by ring-closing metathesis. Application to the total synthesis of lactimidomycin. Author: Gallenkamp D, Fürstner A. Journal: J Am Chem Soc; 2011 Jun 22; 133(24):9232-5. PubMed ID: 21604689. Abstract: Strategic positioning of a silyl group on the diene unit of a diene-ene substrate allows rigorous regio- and stereocontrol to be exerted during metathesis-based macrocyclization reactions. The versatility of this concise approach to E,Z-configured 1,3-dienes of ring sizes of 12 or larger is demonstrated by an application to the total synthesis of lactimidomycin, a potent translation and cell-migration inhibitor.[Abstract] [Full Text] [Related] [New Search]
