  Syntheses of β- and γ-fluorophenyl cis- and trans-α-methylene-γ-butyrolactones

  摘要：

  Preparation of a series of cis-gamma-fluorophenyl-beta-phenyl-alpha-methylene-gamma-butyrolactones is reported via 'allylboration' of fluorobenzaldehydes with (E)-methyl 3-phenyl-2-((4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)methyl)acrylate. The corresponding trans-gamma-fluorophenyl lactones were prepared either (i) via 'allylboration' using the (Z)-reagents or (ii) via an indium triflate-mediated isomerization of the cis-products. The difficulty in isomerizing difluorinated cis-products confirms the probable intermediacy of carbocations. Finally, the synthesis of cis-beta-fluorophenyl-gamma-phenyl-alpha-methylene-gamma-butyrolactones was achieved via an indium-catalyzed allylation-lactonization of aldehydes with (Z)-2-(bromomethyl)-3-(fluorophenyl)acrylates.

  straightforward method for the synthesis of N-substituted imidazole derivatives. 1,1-carbonyldiimidazole mediates the process, which requires no activation group step. We obtained imidazole derivatives in high yields and with short reaction times. To demonstrate the synthetic significance of the aforementioned compounds, we also describe the synthesis of novel ionic liquids from these derivatives.

• Ozonolysis of Morita–Baylis–Hillman adducts originated from aromatic aldehydes: an expeditious diastereoselective approach for the preparation of α,β-dihydroxy-esters

  We disclose herein ozonolysis of Morita-Baylis-Hillman adducts originated from aromatic aldehydes. This efficient reaction provides alpha-ketoesters with different substitution patterns on the aromatic ring. Diastercoselective reduction of the corresponding alpha-ketoester obtained in the oxidative cleavage step provides alpha,beta-dihydroxy-esters with excellent degree of anti diastereoselection. The method is simple and easy to execute and is therefore a valuable alternative to prepare either alpha-ketoesters or alpha-dihydroxy-esters. (c) 2007 Elsevier Ltd. All rights reserved.

  An improved and highly efficient synthesis of several alpha-benzyl-beta-ketoesters from Morita-Baylis-Hillman adducts is described. These adducts were used as substrates for an intermolecular Heck reaction catalyzed by a Najera oxime-derived palladacycles. These efficient catalytic conditions probed to be very selective providing only the corresponding functionalized beta-ketoesters in high yield with no decarboxylation product. It seems that the method herein described is one of the most efficient for the synthesis of alpha-benzyl-beta-ketoesters. (C) 2009 Elsevier Ltd. All rights reserved.
