摘要：

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 HgCl2 eliminates the environmental hazard of heavy-metal waste without appreciable loss of yield or reactivity. This protocol provides an alternative route for the guanylation of amines from those currently employed.
