  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.

  Variant G74C of arylmalonate decarboxylase (AMDase) from Bordatella bronchoseptica has a unique racemising activity towards profens. By protein engineering, variant G74C/V43A with a 20‐fold shift towards promiscuous racemisation was obtained, based on a reduced activity in the decarboxylation reaction and a two‐fold increase in the racemisation activity. The mutant showed an extended substrate range

  支气管败血波氏杆菌中的芳基丙二酸脱羧酶（AMDase）G74C变体对profens具有独特的消旋作用。通过蛋白质工程，基于脱羧反应的活性降低和消旋活性的两倍提高，获得了向混杂消旋化20倍的变体G74C / V43A。该突变体显示出扩大的底物范围，对酮洛芬的反应速率提高了30倍。分子动力学模拟和消旋酶的底物特征表明，底物结构的空间和极性效应在催化方面比单纯的动力学α-质子酸度起着更大的作用。β，γ-不饱和羧酸的转化不会导致重排形成其α，β异构体的观察结果表明，这是一个协调的机制，而不是逐步的机制。有趣的是，

  CH and CH2 groups attached to a heterocycle and a nitro function were rapidly mono- or difluorinated by reaction with 1-chloromethyl-4-fluoro-1,4-diazoniabicyclo[2,2,2]octane bis-tetrafluoroborate (Selectfluor) in the presence of 1,8-diazabicyclo [5.4.0]undec-7-ene (DBU), preferably with Ultrasonic irradiation.
