Magnesium methoxide is a simple, effective and highly selective reagent for the deprotection of N-alkoxycarbonyl lactams. The cleavage occurs via six-membered ring transition states involving coordination of magnesium ion with the oxygens of the carbamate and lactam carbonyl groups.

us to obtain 2-pyrrolidones with oxo and cyano groups in the substituent at the nitrogen atom, because the reduction amination process was accompanied by hydrogenation of these functional groups. Introduction of an oxoalkyl substituent at the nitrogen atom of pyrrolidin-2-ones offers the possibility to modify their structures by reactions involving the oxo group, which leads to the synthesis of new
