A convenient one-step synthesis of five-membered or six-membered imino-protected cyclicguanidine via an intramolecular ring-closure reaction of alkyl diamine (2a–2g) with 1, 3-diamino-protected methylisothiourea (1a and 1b) was established and investigated. Amino guanidine such as 3-(2-aminoethyl)-1, 2-dibenzyloxycarbonylguanidine (4a) has been proved to be the intermediate of the reaction via utilizing
