  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.

  A series of thio-substituted pyrimidine, benzoxazole, benzothiazole and triazole analogues were synthesized from Baylis-Hillman bromides in a clean and efficient way. The synthesized twenty new compounds were subjected to in vitro COX-1 and COX-2 inhibitory activity. Majority of compounds found to be highly selective COX-2 inhibitor. Seven compounds (16e, 16f, 16k, 16l, 16m, 16r and 16s) displayed anti-inflammatory activity at micromolar concentrations with IC50 values for COX-2 inhibition ranging from 2.93 to 5.34 mu M compared to reference drug whose IC50 is 2.66 mu M. All these seven compounds had very little COX-1 inhibition property and thus are suitable candidates for anti-inflammatory drugs with less gastrointestinal side effect. (c) 2014 Elsevier Ltd.

  Twelve tetraphenylphosphonium allyldithiocarbimates were synthesized and fully characterized by high-resolution electrospray ionization mass spectrometry (HR-ESI-MS), infrared and nuclear magnetic resonance (NMR) spectroscopies. The spectroscopic data indicated that the allyldithiocarbimate anions present Z configuration, as confirmed by X-ray crystallography. These new compounds inhibited the germination of Phakopsora pachyrhizi and Hemileia vastatrix at very low doses, with IC50 (concentration to achieve 50% of inhibition of spore germination) values ranging from 0.028 to 0.166 mmol L-1, and IC50 (concentration to achieve 90% of inhibition of spore germination) values varying from 0.156 to 0.528 mmol L-1. Allyldithiocarbimate salts are lead compounds for the development of new antifungals for coffee leaf rust and Asian soybean rust. devastating plant diseases with limited control options.
