The copper-catalyzed direct alkynylation of azoles with 1,1-dibromo-1-alkenes as electrophiles is described. These easily accessible substrates are a useful addition to the field of direct alkynylations in an efficient and functional group tolerant reaction to provide a straightforward entry to diverse alkynyl heterocycles.
本文描述了铜催化唑与 1,1-二溴-1-烯烃作为亲电试剂的直接炔基化反应。这些易于获得的底物是直接炔基化反应领域的有用补充,在高效和官能团容忍的反应中提供了直接进入各种炔基杂环的途径。
