A simple one-pot synthesis of triflyl guanidines: access to highly substituted electron-poor guanidines
摘要:
Unsymmetrical di- and trisubstituted triflyl guanidines are accessed through a simple, one-pot protocol from the corresponding isothiocyanate and amine. Furthermore, in the presence of base, trisubstituted triflyl guanidines are alkylated to obtain tetrasubstituted triflyl guanidines in high yields and complete regioselectivity (C) 2009 Elsevier Ltd.
