SYNTHESIS AND CHARACTERIZATION OF PYRROLINONECARBOXYLATES FORMED BY REACTION OF VICINAL TRICARBONYL DERIVATIVES WITH ALDEHYDE SCHIFF BASES

Wasserman, Harry H.,Ennis, David S.,Vu, Chi B.,Schulte, Gayle,Munk, Morton E.,et al.

, p. 975 - 995 (2007/10/02)

A series of vicinal tricarbonyl derivatives undergo reaction with aldehyde Schiff bases forming pyrrolinone derivatives by benzilic acid-related rearrangements.The structures were established by X-ray analyses and, independently by the SESAMI NMR-based computer program.
