摘要：

The synthesis of a polymer-supported Mukaiyama reagent is described. This preparation was thoroughly optimized using a DoE approach to achieve optimum loading, and the procedure was successfully applied to prepare the supported reagent on a 10 g scale. This reagent proved to be effective for the formation of carbodiimides through the dehydration of thioureas and for a one-pot guanylation of primary amines. (C) 2004 Elsevier Ltd.
