An efficient approach to thiazolo[4,5-b]azepine-5,8-diones and thieno[3,2-b]azepine-5,8-diones has been developed via a domino synthesis of multifunctionalized thiazoles/thiophenes and further intramolecular cyclization. This transformation proceeded rapidly under mild conditions without use of metal catalyst.
通过多官能团噻唑/噻吩的多米诺合成以及进一步的分子内合成,已开发出一种有效的方法来处理噻唑并[4,5 - b ]氮杂5,8-二酮和噻吩并[3,2 - b ]氮杂5,8-二酮环化。在不使用金属催化剂的情况下,该转化在温和条件下迅速进行。
