A series of C-5 substituted pyrrolizine biscarbamate alkylating agents were synthesized and evaluated in an in vitro alkylation assay. Introduction of electron-withdrawing substituents at the C-5 position resulted in a dramatic decrease in chemical reactivity toward the model nucleophile 4-(4-nitrobenzyl)pyridine (NBP).
合成了一系列C-5取代的吡咯嗪双氨基甲酸酯烷基化剂,并在体外烷基化测定中进行了评估。在C-5位引入吸电子取代基导致对模型亲核体4-(4-硝基苄基)吡啶(NBP)的化学反应性显着降低。
