Tandem metal relay catalysis: from cyclopropene to polysubstituted furan
Abstract
Transmetalation is a key step in traditional coupling reactions. Herein we discuss the most recent progress in the metal–metal relay catalysis based on a transmetalation strategy. An efficient synthetic strategy for the formation of polysubstituted furan derivatives from cyclopropenes based on the tandem metal relay catalysis (TMRC reaction) is summarized.
