摘要

A reliable procedure for the preparation of the chiral Lewis acid catalysts,(-)-menthoxy-((-)-1) and (-)-bornyloxy-aluminum dichloride ((-)-2), has been established for the study of diene additions. The geometry of conformationally mobile α, β-unsaturated carbonyl compounds complexed with these catalysts has been probed using the α-methylene ketones 3 and 4 and 2, 6-dimethyl-1, 4-benzoquinone 5 as dienophiles of fixed geometry. The addition of ...
