چکیده انگلیسی
Oxidative alkylamination of azinones is a promising method for the preparation of a great variety of alkylaminoazinones. Treatment of 6,8-dimethyl-2-R-pyrimido[4,5-c]pyridazin-3,5,7(2H,6H,8H)-triones 7, 1,3-dimethyl-5-R-pteridin-2,4,6(1H,3H,6H)-triones 8 and 1,3,6-trimethylpyrimido[4,5-d]pyrimidin-2,4,7(1H,3H,6H)-trione 9 with alkylamine/AgPy2MnO4 or alkylamine/KMnO4 has been shown to produce their 4-, 7- and 5-alkylamino derivatives, respectively, in good yields. While 1-methylquinoxalin-2(1H)-one 10 is smoothly alkylaminated under the above conditions giving 3-alkylamino derivatives, quinoxaline itself does not take part in this reaction. Factors influencing oxidative alkylamination of azinones and a regioselectivity of the process are discussed.
