Chiral relay effect: 4-substituted 1,3-benzoxazol-2-(3H)-ones as achiral templates for enantioselective Diels-Alder reactions

Quaranta, Laura,Corminboeuf, Olivier,Renaud, Philippe

, p. 39 - 41 (2007/10/03)

(matrix presented) A new strategy to control the enantioselectivity of Lewis acid catalyzed reactions has been investigated. The use of N-acryloyl-1,3-benzoxazol-2-(3H)-ones substituted at position 4 leads to the formation of diastereomeric complexes as a
