The enantioselective Diels-Alder reaction of N-propenoyl-1,3- oxazolidin-2-one with cyclopentadiene was catalyzed by free and polymer- supported complexes of titanium with N-sulfonyl-L-amino acids. The L- amino acids used in this study were valine, phenylalanine, leucine and isoleucine. The ee values of the reactions catalyzed by the free and polymer-supported complexes were 48.1% ~ 78.2% and 82.8% ~ 84.5%, respectively.

Key words: AMINO ACID, OXAZOLIDINONE P, CYCLOPENTADIENE, VALINE, PHENYLALANINE, LEUCINE
