Abstract :
The enantioselective addition of allyltributyltin to simple aldehydes (2a-l), catalyzed by chiral (salen)Cr(III) complexes 1, has been studied. The reaction proceeds smoothly with low loading (1-2 mol%) of (salen)Cr(III)BF4 (1a) and allyltributyltin under high-pressure conditions (10 kbar) in good yield and ee values in the range of 35-79%.
