Synthesis of amidoglucals and glucal esters via carbonylative coupling reactions of 2-iodoglucal using Mo(CO)6 as a CO source

ABSTRACT

The synthesis of amidoglucals and glucal esters in good to high yields using 2-iodo-3,4,6-tri-O-acetyl-d-glucal as a substrate, Mo(CO)(6) as a carbon monoxide source and PdCl2 as a catalyst is reported. This procedure shows advantages when compared to other published methodologies, as it is carried out in one pot relying on short reaction times at mild temperatures, under ligand-free conditions and with only one equivalent of Mo(CO)(6).
