摘要
Cheap and cheerful: The Zn(OTf)2-catalyzed guanylation/amidation from readily available amino acid esters and carbodiimides has been achieved to efficiently provide various cyclic oxoguanidines (see scheme). It is the first time that an ammonium salt has been used in the guanylation reaction. Application of cyclic oxoguanidines is explored to provide conjugated heterocyclic compounds through oxidative C[BOND]N formation or aldol reactions.
