A novel photoinduced strategy has been developed for the C-H amidation of aromatics and heteroaromatics by using benzamide radicals such as 1,3,5-trimethylbenzene, 1-methoxynaphthalene, 1-methyl-1H-indole, 1-methyl-1H-pyrrole, etc. with free NH groups generated from N-amidopyridinium salts such as as 1-benzamido-2,4,6-triphenylpyridin-1-ium tetrafluoroborate under visible-light irradiation The new mode of activation of N-amidopyridinium salts proceeds efficiently under mild conditions to give various benzamide derivatives RNHC(O)C6H5 (R = 2,4,6-trimethylphenyl, 1-methoxynaphthalen-2-yl, 1-methyl-1H-indol-3-yl, etc.) with free NH groups. In addition, oxazoline analogs, synthesized by the reaction with styrene, demonstrate a substantial range of prospective applications for this versatile protocol.
Synlett published new progress about 93-04-9. 93-04-9 belongs to ethers-buliding-blocks, auxiliary class Naphthalene,Ether, name is 2-Methoxynaphthalene, and the molecular formula is C5H5NO3S, Application of 2-Methoxynaphthalene.
