Abstract

Irradiation in water.-saturated ehyl ether of isoxazolopyridines 1a,e, beside the corresponding oxazolopyridines 2a,e, leads to N-methylcarboxamides 3a,e via 1-2 shift of the methyl group. The lsoxazolopyridine 5, bearing a hydrazino group in 4-position, rearranges only to 1-aminopyrazolopyridine 6.
