  Diastereoselection in the Lewis acid catalyzed cycloaddition reaction of .alpha.-alkoxy imines

  摘要：

  The Lewis acid catalyzed cycloaddition reactions of alpha-benzyloxy imines (RCH(OCH2C6H5)CH = NCH2C6H5) were investigated using 1,3-dimethoxy-1-[(trimethylsilyl)oxy]-1,3-butadiene. The observed diastereoselectivity was dependent on both the Lewis acid and substrate structure. Strong Lewis acids such as diethylaluminum chloride (DEAC) exhibited moderate to good success in promoting the cycloaddition reaction. When DEAC was used as the Lewis acid, the diastereoselectivity was also dependent on the stoichiometry of the Lewis acid to the substrate. In general, the diastereoselectivity increased with increasing steric bulk of the R group.
