The synthesis of 7-membered cyclic sulfamides utilizing the RCM reaction is described herein. Two major synthetic strategies that expand the scope and utility of our previously reported sulfamide and sulfamoyl carbamate chemistry are employed. Both Mitsunobu alkylation and simple alkylation of core sulfamides and sulfamoyl carbamates coupled with RCM are used to efficiently install lipophilic groups
本文描述了利用RCM反应的7元环硫酰胺的合成。使用了两种主要的合成策略,这些策略扩大了我们先前报道的氨磺酰胺和氨基磺酸氨基磺酰基化学反应的范围和实用性。Mitsunobu烷基化以及核心磺酰胺和氨基甲酸酯氨基甲酸酯与RCM的简单烷基化都可用于将亲脂性基团有效地安装到环状磺酰胺的P1 / P1'和P2 / P2'外围。总体而言,所描述的路线适用于各种环状7元磺酰胺的合成。
