  摘要：

  The reaction between 1 3-cyclohexanediones and chalcones (or their vinilogs) in the presence of 2 5 equiv of cerium(IV) ammonium nitrate afforded trans-2-arylcarbonyl-3-aryl (or styryl)-2 3 6 7-tetrahydrobenzofuran-4(5H)-ones in good to excellent yields and in high diastereoselectivities The method was also extended to the preparation of derivatives of the 5 6-dihydro-2H-cyclopenta[b]furan-4(3H)-one system The fused 2 3-dihydrofuran derivatives were transformed into 1-alkyl-2-acyl-3-aryl-6 7-dihydroindole-4(5H)-ones by 2 3-dehydrogenation followed by reaction with primary amines The direct reaction of the tetrahydrobenzofuran-4(5H)-one compounds derived from dimedone with amines gave 1-alkyl-2-alkylimino-3-aryl-6 7-dihydroindole-4(5H)-ones while starting materials derived from 1 3-cyclohexanedione underwent an unprecedented 2-deacylation reaction and gave 1-alkyl-3-aryl-6 7-dihydroindole-4(5H)-ones (C) 2010 Elsevier Ltd All rights reserved
