Novel Rearrangement of 3‐Acylaminofuro[2,3‐b]pyridines into 3‐(oxazol‐4‐yl)pyridin‐2‐ones

“…First, this transformation looks like a widely used Robinson-Gabriel oxazole synthesiscyclodehydration of N-acylaminoketones [28][29][30][31][32][33][34][35][36][37], where furan moiety can act as a source of carbonyl group. However, unlike the said method required such as acidic dehydrating agents as acetic anhydride, P 2 O 5 , PPA, triflic anhydride, this transformation proceeds under basic conditions.…”
