Allin, Steven M., Northfield, Christopher J., Page, Michael I. and Slawin, Alexandra M.Z. (1999) A highly diastereoselective synthesis of 3-substituted isoindolin-1-one dericatives. Tetrahedron Letters, 40 (1). pp. 143-146. ISSN 0040-4039

A highly diastereoselective method for the synthesis of 3-substituted isoindolin-1-ones has been developed through application of a tricyclic lactam substrate as an N-acyliminium ion precursor. Ring-opening of the tricyclic lactam with triethylsilane as hydride source generates the targets with up to exclusive levels of diastereoselectivity. This approach compliments that reported in the preceding paper.
