Wang, Zhan-Yong; Yang, Ting; Wang, Kai-Kai; Chen, Rongxiang; Liu, Menghan; Liu, Hongxin published the artcile< Oxidative N-heterocyclic carbene-catalyzed [3 + 3] annulation reaction of enals with benzofuran-3-ones: efficient access to benzofuran-fused δ-lactones>, COA of Formula: C9H7BrO, the main research area is benzofuranone enal azacyclic carbene catalyst heterocyclization; dihydropyranobenzofuranone preparation.
A facile route to benzofuran-fused δ-lactones was developed via an N-heterocyclic carbene-catalyzed [3 + 3] annulation reaction, giving the expected products in high yields (up to 99%) with excellent enantioselectivities (up to 98% ee). It should be noted that benzofuran-fused pyrones can be obtained stepwise in one pot with excellent yields (up to 96%) by using this methodol.
Organic Chemistry Frontiers published new progress about Benzofurans Role: RCT (Reactant), RACT (Reactant or Reagent). 3893-18-3 belongs to class bromides-buliding-blocks, and the molecular formula is C9H7BrO, COA of Formula: C9H7BrO.
