Convenient synthesis of acyclic guanidines from isothiouronium iodides and amines without protection of the amino groups

Aoyagi, Naoto,Furusho, Yoshio,Endo, Takeshi

, p. 983 - 986 (2014/05/06)

Acyclic guanidines were obtained in one step by reaction of isothiouronium iodides with an equimolar amount of various amines in tetrahydrofuran. The reactions proceeded under ambient conditions without N-protection/deprotection to afford the corresponding substituted guanidines in quantitative yields. Georg Thieme Verlag Stuttgart New York.
