Recyclable [bmIm]OH promoted one-pot heterocyclization: synthesis of substituted benzofurans
摘要:
A single step access to polysubstituted benzo[b]furans has been achieved under simple and eco-compatible conditions. The heterocyclization proceeded efficiently. [bmIm]OH played a triple role as a solvent, base as well as catalyst. (C) 2013 Elsevier Ltd. All rights reserved.
