Catalyst prepared according to the formula (1): 2 A1H3 + Ar(-OH)2 + 2Rc-OH + 2HC1; where Rc is a chiral alcohol selected from the group consisting of diacetone-D-glucose, diacetone-D-allofuranose, norborneol, isocamphenol and menthol and Ar is chiral diol whose chirality is caused by restricted rotation about a single bond. These catalytic compounds are useful in catalyzing asymmetric Diels-Alder reactions.
