for the synthesis of a variety of elusive furo[2,3-b]pyrrole and thieno[2,3-b]pyrrole libraries has been established. To date, cyclization among alkanone, hydrazine and 2-bromobenzofuran or 2-bromobenzo[b]thiophene has not been explored in one-pot. Thus, the proposed single step protocol provides a versatile alternative to existing routes for accessing useful furo[2,3-b]pyrrole and thieno[2,3-b]pyrrole
建立了一种新颖的I 2催化一锅多组分方案,用于合成各种难以捉摸的呋喃[2,3- b ]吡咯和噻吩并[2,3- b ]吡咯文库。迄今为止,尚未在一锅中研究烷酮,肼和2-溴苯并呋喃或2-溴苯并[ b ]噻吩之间的环化。因此,提出的单步协议为访问有用的呋喃[2,3- b ]吡咯和噻吩并[2,3- b ]吡咯文库提供了一种替代现有途径的通用选择。
