摘要：

Here is described a high yield synthesis of 4-(tert-butoxycarbonyl)-3-[(diphenoxyphosphoryl)oxo]-4H-pyrido[3,2-b][1,4]oxazine from a pyridoxazin-3-one derivative. The hydrogenolysis of this compound provides a convenient route to 4H-pyrido[3,2-b][1,4]oxazine and palladium-catalysed coupling reactions between this vinylphosphate and organostannanes gained access to 3-substituted-4H-pyrido[3,2-b][1,4]oxazines,
