An effective one-flask multicomponent linchpin coupling protocol employing the concept of anionrelaychemistry (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
