Synthesis of β-acylamino furans from glucosamine

A facile method for the synthesis of a series of novel β-acylamino furans stating from renewable monosaccharide was achieved. Glucosamine hydrochloride was selectively N-acylated with acyl chlorides in methanol/triethylamine to yield N-acyl-d-glucosamines, which were subsequently converted into β-acylamino furans through dehydration and cyclization under microwave irradiation.
