A number of simple silyl enol ethers and vinyl trifluoromethanesulfonates, a relatively new class of organic compounds capable of undergoing alkylation by a nucleophilic addition-elimination process, were evaluated in the P388 lymphocytic leukemia system. No activity (ILS = 8-22%) was observed in the simple vinyl derivatives. Some activity (ILS = 20-42%) was observed for a series of siloxy and sulfonate
在P388淋巴细胞白血病系统中评估了许多简单的甲硅烷基烯醇醚和三氟甲基磺酸乙烯基酯,它们是一类相对较新的能够通过亲核加成消除反应进行烷基化的有机化合物。在简单的乙烯基衍生物中未观察到活性(ILS = 8-22%)。对于一系列甲硅烷氧基和磺酸盐(CH3SO2和CF3SO3)官能化的α-亚甲基内酯体系,观察到一些活性(ILS = 20-42%)。功能性系统相对于母体亚甲基内酯的增强的活性归因于细胞亲核试剂经由亲核加成消除过程可能发生的不可逆烷基化。
