Synthesis and Mechanistic Study of Cyclic Oxoguanidines via Zn(OTf)2 -Catalyzed Guanylation/Amidation from Readily Available Amino Acid Esters and Carbodiimides. Chemistry (Weinheim an der Bergstrasse, Germany), 2015, Jul-13, Volume: 21, Issue:29 The Zn(OTf)2 -catalyzed guanylation/amidation from readily available amino acid esters and carbodiimides is achieved to provide efficiently various cyclic oxoguanidines, including 2-amino-1H-imidazol-5(4H)-ones and 2-aminoquinazolin-4(3H)-ones in medium-to-high yields. It is the first time that an ammonium salt has been used in a guanylation reaction. The application of cyclic oxoguanidines to provide the conjugated heterocyclic compounds via oxidative C-N formation or aldol reaction is explored. The reaction mechanism is well elucidated by the isolation and characterization of three important intermediates.
