  A simple synthesis of fluoroalkyl substituted dihydrofurans by rhodium(II)-catalyzed 1,3-dipolar reactions

  摘要：

  The rhodium(II)-catalyzed reactions of ethyl 2-diazo-fluoroalkylacetoacetate 1 with vinyl ethers have been studied. The reactions of 1a-e with isobutyl vinyl ethers afforded dihydrofuroates 3a-e in good to excellent yields. Further transformation of the dihydrofuroates by acid-catalyzed alcohol elimination could give alpha -fluoroalkyl-beta -furoates readily. Similarly, stable diazo compounds 1a and b reacted with cyclic vinyl ethers to give 1,3-dipolar cycloaddition products. Interestingly, only vinyl C-H insertion compound was obtained concerning the reaction of la with 2,5-dimethylfuran. The reaction mechanism was also discussed. (C) 2001 Elsevier Science Ltd.
