  Fluorination and chlorination of nitroalkyl groups

  摘要：

  Heterocycles substituted with a nitromethyl (CH2NO2) or phenyl-nitromethyl (CHPhNO2) group were prepared by reaction of a methyl- or phenylmethyl-substituted heterocycle, respectively, with lithium di-isopropylamide followed by quenching the intermediate carbanion with methyl nitrate. Conversion of CH2NO2 attached to an alkyl or aryl moiety into a dichloronitromethyl (CCl2NO2) group was achieved using N-chlorosuccinimide and 1,8-diazabicyclo[5.4.0] undec-7-ene (DBU) in dichloromethane. Similarly, CH2NO2 attached to an alkyl or aryl group was converted into difluoronitromethyl (CF2NO2) using either 1-chloromethyl-4-fluoro-1,4-diazoniabicyclo[2.2.2]octane bis( tetrafluoroborate) (Selectfluor (TM)) or N-fluorobenzenesulfonimide with DBU as base and dichloromethane as solvent. Reaction of omega-nitroacetophenone with Selectfluor/DBU in dimethylformamide followed by acidification and distillation gave the parent difluoronitromethane in a useful 'one-pot' procedure.

• Homogeneous catalysis, heterogeneous recycling: a new family of branched molecules with hydrocarbon or fluorocarbon chains for the Friedländer synthesis of quinoline under solvent-free conditions

  A new family of branched catalysts with hydrocarbon or fluorocarbon chains was used to catalyze Friedländer reaction between 2-aminoarylketones and α-methylene ketones under solvent-free conditions in good to excellent yields. The catalysts exhibit temperature-dependent solubility and such a thermomorphic character allows them to be recovered by filtration conveniently at room temperature and reused

  在无溶剂条件下，使用新的具有烃或碳氟化合物链的支化催化剂家族来催化2-氨基芳基酮和α-亚甲基酮之间的Friedländer反应，产率高至优异。催化剂表现出随温度变化的溶解度，并且这种热定形特性使其可以通过在室温下方便地过滤回收并至少重复使用五次。在某种程度上，具有烃链的支链催化剂比具有碳氟化合物链的支链催化剂优越，因为它们更便宜且可生物降解。

  A convenient and efficient method was developed for the synthesis of quinolines, an important class of potentially bioactive compounds. The quinoline derivatives were prepared in water, an excellent solvent in terms of environmental impact and with reduced waste production. PEG-SO3H effectively catalysed the one-pot synthesis of quinolines by the condensation of o-aminoaryl ketones and carbonyl compound with high yields (75–95%). The compounds were isolated by simple filtration in a high purity form.
