A novel and efficient methodology for the synthesis of 1,2,3-trisubstituted pyrroles by one-pot two-step reaction has been developed. The iodocyclization of a series of β-enamino esters followed by dehydroiodination, led to the formation of corresponding pyrroles. This approach provides an easy access to a wide range of 1,2,3-trisubstituted pyrroles.
通过一锅两步反应合成1,2,3-三取代的吡咯的一种新颖而有效的方法已经被开发出来。一系列β-烯氨基酯的碘环化,然后进行脱氢碘化作用,导致形成相应的吡咯。这种方法可轻松获得各种1,2,3-三取代的吡咯。
