摘要

Abstract A regioselective synthesis of 2-aminotriazinones 6a-d is reported, by reaction of 3- methylthio-1, 2, 4-triazinones 5a-d with O-(2, 4-dinitrophenyl) hydroxylamine (2) as an amino- transfer agent. A spectroscopic study and an unequivocal synthesis of 2-amino-4-methyl-6- phenyl-1, 2, 4-triazinedione (11a) has shown the site of amination to be N2 of the 1, 2, 4- triazinone ring. Subsequent reaction of 2-amino-1, 2, 4-triazinones 6a-b with amines, ...
