Macrocyclization of di-Boc-guanidino-alkylamines related to guazatine components: Discovery and synthesis of innovative macrocyclic amidinoureas

Castagnolo, Daniele,Raffi, Francesco,Giorgi, Gianluca,Botta, Maurizio

supporting information; experimental part, p. 334 - 337 (2009/06/18)

The synthesis of new and innovative macrocyclic amidinoureas from linear di-Boc-guanidino-alkylamines related to guazatine was accomplished. The macrocyclization reaction proceeds under mild conditions affording 11- to 16-membered rings with a new and pre
