Abstract

Among various aldiminato metal complexes, the optically active cobalt(II) complex efficiently catalyzed the enantioselective hetero Diels- Alder reaction of aromatic aldehydes with 1-methoxy-[3-(tert- butyldimethylsilyl)oxy]1,3-butadiene. In the presence of 0.5 mol% of the catalyst, the reaction smoothly proceeded and ortho substituents of the dienophiles that could chelate to the catalyst significantly accelerated the reaction to improve the chemical and optical yields.
