N-acyliminium-ion induced intermolecular electrophilic aromatic substitution yielding nitrogen-substituted phenylglycine derivatives, whereas the benzylamide of glyoxylic acid-2-pyrrolidinone adduct undergoes intramolecular amidoalkylation to give an isoquinolone type compound. High stereospecifity and enantioselectivity was observed in intermolecular amidoalkylation of benzene using glyoxylic acid-S-pyroglutamic
乙醛酸-2-吡咯烷酮加合物导致N-酰基亚胺离子诱导的分子间亲电芳族取代,产生氮取代的苯基甘氨酸衍生物,而乙醛酸-2-吡咯烷酮加合物的苄酰胺进行分子内酰胺烷基化,得到异喹诺酮型化合物。使用乙醛酸-S-焦谷氨酸酯或酰胺加合物在苯的分子间酰胺烷基化中观察到高的立体选择性和对映选择性。
