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.
The Conversion of Carboxylic Acids to Keto Phosphorane Precursors of 1,2,3-Vicinal Tricarbonyl Compounds
Wasserman, Harry H.,Ennis, David S.,Blum, Charles A.,Rotello, Vincent M.
, p. 6003 - 6006 (2007/10/02)
Acyl phosphoranylidines react with acid chlorides or anhydrides in the presence of bis(trimethylsilyl)acetamide (BSA), or couple directly with carboxylic acids activated by EDCI to give keto phosphoranes 1.
BENZILIC ACID REARRANGEMENTS IN THE REACTIONS OF ARYL VICINAL TRICARBONYL DERIVATIVES WITH ALDEHYDE SCHIFF BASES
Wasserman, Harry H.,Ennis, David S.,Vu, Chi B.,Schulte, Gayle K.
, p. 6039 - 6042 (2007/10/02)
Reactions of aryl and hetero vicinal tricarbonyl derivatives with aldehyde Schiff bases of the general structure RCH2CHO lead to pyrrolinone derivatives by benzilic acid-related rearrangements, driven, most probably, by iminium ion intermediates.
