From domino to multicomponent: synthesis of dihydroisobenzofurans
摘要:
A variety of substituted dihydroisobenzofurans can be easily synthesized in high yields by a one-pot three-component approach starting from o-bromoarylaldehydes, methanol, and terminal alkynes. The reaction occurs through an unprecedented cooperative palladium/base promoted coupling/addition/cyclization sequence. (C) 2010 Elsevier Ltd. All rights reserved.
