The Rh2(OAc)4 -catalysed CH insertion reaction in chiral ester diazoanilides was investigated and was found to yield 4-substituted 2-pyrrolidinones with moderate to high e.e. (37–98 %) after decarbalkoxylation. Electronic effects were found to oppose steric effects in influencing the enantioselectivity of the reaction in N-arylethyl diazoanilides.
研究了Rh 2(OAc)4催化的手性酯重氮苯胺化物中的CH插入反应,发现该化合物在脱碳烷氧基化后可产生具有中等至较高ee(37-98%)的4-取代的2-吡咯烷酮。发现在影响N-芳基乙基重氮苯胺中反应的对映选择性方面,电子效应与空间效应相反。
