Synthesis of 3-substituted-4H-1,4-benzoxazines via palladium-catalysed coupling reactions

Article abstract of DOI:10.1016/S0040-4039(98)02453-8

Here is described a high yield synthesis of 3-substituted 4H-1,4- benzoxazines via palladium-catalysed coupling reactions between organostannanes and a vinylphosphate obtained from a benzoxazin-3-one derivative.
