ChemInform Abstract: Hypervalent Iodine-Mediated Intramolecular trans-Aminocarboxylation and Oxoaminocarboxylation of Alkynes: Divergent Cascade Annulations of Isocoumarins under Metal-Free Conditions.
The trans-aminocarboxylation of alkynes is performed following a two-pot two-step reaction procedure while delivering fused polyheterocyclic compounds in high yields.
