Synthesis of α-amino amidines through molecular iodine-catalyzed three-component coupling of isocyanides, aldehydes and amines
A facile and efficient synthetic protocol for the synthesis of α-amino amidines has been developed using a molecular iodine-catalyzed three-component coupling reaction of isocyanides, amines, and aldehydes. The presented strategy offers the advantages of mild reaction conditions, low environmental impact, clean and simple methodology, high atom economy, wide substrate scope and high yields
Rapid Access to Novel 1,2,3-Triazolo-Heterocyclic Scaffolds via Tandem Knoevenagel Condensation/AzideâAlkyne 1,3-Dipolar Cycloaddition Reaction in One Pot
An
operationally simple, one-pot, two-step cascade method has been
developed to afford biologically important fused 1,2,3-triazolo-heterocyclic
scaffolds from 2-alkynyl arylÂ(heteroaryl) aldehydes and phenacyl azides.
This unique atom economical transformation engages four reactive centers
(aldehyde, alkyne, active methylene, and azide) under metal-free catalysis
