A novel and efficient synthetic procedure for converting a diverse set of amines to N,N′ -di-Boc-protected guanidines is described. The methodology comprises the use of cyanuric chloride (TCT) as activating reagent for di-Boc-thiourea. The employ of inexpensive TCT instead of classical HgCl 2 eliminates the environmental hazard of heavy-metal waste without appreciable loss of yield or reactivity. This
描述了一种将多种胺转化为 N,N' -di-Boc 保护的胍的新型有效合成程序。该方法包括使用氰尿酰氯 (TCT) 作为二-Boc-硫脲的活化剂。使用廉价的 TCT 代替经典的 HgCl 2 消除了重金属废物对环境的危害,而不会显着降低产量或反应性。该协议为目前使用的胺类鸟苷酸化提供了另一种途径。
