This paper describes a general procedure for the synthesis of new substituted thiaisatoic anhydrides or 6- or 7-aryl-1H-thiéno[3,2-d][1,3]oxazine-2,4-diones 3a–j and 4a–f. They were synthesized in large scale under microwave heating conditions with high yields. The reactivity vs nucleophilic reagents of these compounds was studied and permitted to develop a simple combinatorial procedure to synthesize
本文描述了合成新的取代硫代硫杂酸酐或6-或7-芳基-1 H-噻吩并[3,2- d ] [1,3]恶嗪-2,4-二酮3a – j和4a的一般程序。 – f。它们在微波加热条件下以高收率大规模合成。研究了这些化合物的亲核试剂的反应性与亲核试剂的关系,并允许开发一种简单的组合方法来合成新的噻吩脲酸7a – j和8a – j库。
