A novel methodology for the synthesis of guanidines from amines has been developed using polymer assisted synthesis, potentially allowing the preparation of series of compounds in a high throughput manner. The methodology comprises the use of polymer-supported carbodiimide as the activating agent for N,N′-bis(tert-butoxycarbonyl) thiourea with polymer-supported trisamine as a scavenger, followed by
已经开发了使用聚合物辅助合成法从胺合成胍的新方法,潜在地允许以高通量的方式制备一系列化合物。该方法包括使用聚合物负载的碳二亚胺作为N,N′-双(叔丁氧基羰基)硫脲的活化剂,并使用聚合物负载的三胺作为清除剂,然后用三氟乙酸脱保护。首次将聚合物负载的碳二亚胺用作合成胍的活化剂。
