2-Vinyl quinazoline 3-oxides 6a, 6b and 15a are useful modular building blocks for the construction of a range of heterocycles with potential biological activity, from o-[amidoalkenyl]aryloximes 5a, 5b and 14a, respectively, by cyclocondensation. Conjugate addition of EtOH or MeOH to the vinyl moiety of 6b is demonstrated.
2-乙烯基喹唑啉3-氧化物6a,6b和15a是有用的模块化构件,用于通过环缩合从邻-[酰胺基烯基]芳基肟5a,5b和14a构建一系列具有潜在生物活性的杂环。证明了将EtOH或MeOH共轭添加到6b的乙烯基部分。
