A synthesis in good to excellent yields of 23 4H-benzo[d][1,3]oxazin-4-ones, 18 of which are novel, from monosubstituted anthranilic acids and variously substituted phenyl isoselenocyanates without using any harsh reagents has been developed. The Se powder precipitated during the reaction could be efficiently recycled for the preparation of the aryl isoselenocyanates.
已经开发出一种从单取代邻氨基苯甲酸和不同取代的异硒氰酸苯基酯合成 23 4H-苯并[d][1,3]恶嗪-4-酮,其中 18 种是新型的,且不使用任何刺激性试剂的合成方法。反应过程中沉淀的硒粉可有效回收用于制备异硒氰酸芳基酯。
