JOURNAL NAME: International Journal of Organic Chemistry, Vol.2 No.1, March 15, 2012 ABSTRACT: The present study reports the reaction of 4-bromomethylcoumarins with salicylidineaniline in acetone with ...

Our studies on the mechanism of the proline-catalyzed aldol reaction began when we found that whereas Agami had demonstrated that the intramolecular Hajos–Parrish–Eder–Sauer–Wiechert reaction ...
