Kj. Wiggall et Sk. Richardson, A VERSATILE SYNTHESIS OF FUNCTIONALIZED 2-AMINOQUINOLINES BY MERCURY CONTROLLED CYCLIZATION OF 2-VINYLPHENYLTHIOUREAS, Journal of heterocyclic chemistry, 32(3), 1995, pp. 867-870
-(4-Hydroxyphenyl)-2-phenylamino-1,8-naphthyridine was prepared via cy
clisation of N'-3-(4-hydroxyphenethen-1-yl)pyridin-2-ylthiourea in the
presence of mercuric oxide. Derivatives of 4-methyl-2-aminoquinolines
were prepared in a similar manner from 2-vinylphenylthioureas.
