were synthesized by [4+2]type cycloaddition of chiral aldimines (5) with 2silyloxy-l,3-butadienes (3) in the presence of Lewis acids. In the cycloaddition, only two 2,6-trans isomers (chelation and nonchelation products) were observed and no cis compounds were detected regardless of the Lewis acid u
