摘要

Cleavage of several 2, 4-dimethoxybenzylmaleimides could be performed employing TFA in anisole. Electronic effects exemplified by varying the substitution present on the maleimide resulted in a variation in the rate of the deprotection. In contrast, 2, 4- dimethoxybenzylsuccinimides were inert to the conditions.
