Abstract
The title compounds having different substituents on the heterocyclic framework were prepared by several methods from 2-acetamido-3-hydroxypyridine. The condensation of 2- protected-amino-3-hydroxypyridine with 2-chloroacrylonitrile or ethyl 2, 3- dibromopropionate provided in several cases two isomeric pyrido-oxazines. Whereas the reaction of 2-acetamido-3-hydroxypyridine with methyl 2, 3-dibromopropionate or with α- ...
