Irradiation in water-saturated ethyl 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 isoxazolopyridine 5, bearing a hydrazino group in 4-position, rearranges only to l-aminopyrazolopyridine 6.

A convenient synthesis of 4-acetyl-3-hydroxypyridine is reported; this compound allows the preparation of the new isoxazolo- and oxazolopyridine ring systems.
