An effective one-flask multicomponent linchpin coupling protocol employing the concept of anion relay chemistry (ARC) was developed. This concept calls for addition of an anion (5) to an epoxide (6), bearing on a distal carbon a trialkyl silyl group and an anion stabilizing group (ASG), to furnish upon epoxide ring opening oxyanion 7. Addition of HMPA or other polar solvents to trigger a solvent controlled
开发了一种采用阴离子继电器化学 (ARC) 概念的有效单瓶多组分关键耦合协议。这个概念要求将阴离子 (5) 添加到环氧化物 (6) 上,在远端碳上带有三烷基甲硅烷基和阴离子稳定基团 (ASG),以在环氧化物开环时提供氧阴离子 7. 添加 HMPA 或其他极性溶剂触发溶剂控制的 1,4-布鲁克重排,然后产生新的远端阴离子 (8),后者又可与各种第二亲电试剂反应。
