Barriers to enantiocontrol in Lewis acid catalyzed hetero-Diels–Alder reactions‡
Literature Information
Xiaochen Wang, Zhuoyan Li, Michael P. Doyle
Lewis bases, including reactant aldehydes, inhibit the rate of conversion for cycloaddition and those, like aldehydes or nitriles, cause a decrease in enantiocontrol due to the Lewis acidity of the activated complex.
