Some ways to use the N-acyl iminium salt methodologies to synthesize a new inhibitor of tubulin polymerization, methyl N-(3,4,4′,5-tetramethoxybenzhydryl)pyroglutamate (HEI 81) were studied. The most interesting reactions utilize a new pyroglutamic lactone (3-(3,4,5-trimethoxyphenyl)dihydropy-rrolo[1,2-c]oxazole-1,5-dione).
研究了使用N-酰基亚胺盐方法合成一种微管蛋白聚合新抑制剂N-(3,4,4',5-四甲氧基苯甲酰基)焦谷氨酸甲酯(HEI 81)的方法。最有趣的反应是利用新的焦谷氨酸内酯(3-(3,4,5-三甲氧基苯基)二氢吡咯并[1,2 - c ]恶唑-1,5-二酮)。
