Synthesis of 2-(Diarylmethylene)-3-benzofuranones Promoted via Palladium-Catalyzed Reactions of Aryl iodides with 3-Aryl-1-(2-tert-butyldimethylsilyloxy)phenyl-2-propyn-1-ones
Synthesis of 2-(Diarylmethylene)-3-benzofuranones Promoted via Palladium-Catalyzed Reactions of Aryl iodides with 3-Aryl-1-(2-tert-butyldimethylsilyloxy)phenyl-2-propyn-1-ones
synthetic strategy for the synthesis of diversely 2,3-disubstitutedbenzofurans is described. This method is based on the use of propargylic alcohols generated from TBS-protected ortho-hydroxy benzaldehydes as starting materials and allows a library of 2,3-disubstitutedbenzofurans to be built. The procedure consists of one-potnucleophilicsubstitution, TBS-deprotection, and exo-dig cycloisomerization
