  New fluorinated derivatives as esterase inhibitors. Synthesis, hydration and crossed specificity studies

  摘要：

  A variety of new fluorinated chemicals have been prepared for the first time and tested as inhibitors of esterases, one of the main enzymes involved in pheromone catabolism, in two economically important pests, the Egyptian armyworm Spodoptera littoralis (SL) and the Mediterranean corn borer Sesamia nonagrioides (SN). Using the respective major component of the pheromone as substrate, the K-m and V-max of the antennal esterase of both insects resulted to be 5.66 x 10(-4) M and 8.47 x 10(-6) Mmin(-1) for SL and 1.61 x 10(-7) M and 1.25 x 10(-7) Mmin(-1) for SN, pointing out that SN esterase has a higher affinity for its corresponding substrate than SL. In general, the trifluoromethyl ketones (TFMKs) exhibited higher inhibitory potency than the corresponding difluoromethyl ketones (DFMKs) or difluoroaldehydes (DFAs). The compounds appeared to hydrate differently in aqueous solution, the extent of hydration following the order: alpha,alpha-DFMKs

• EPR/Spin-trapping study of free radical intermediates in the photolysis of trifluoromethyl ketones with initiators

  detection of the elusive trifluoromethyl radical. In contrast, long-chain TFMKs did not provide clues to prove formation of the trifluoromethyl radical but instead to radicals derived by abstraction of one alpha-methylene proton to the carbonyl. Although TFMKs are quite stable to photodegradation in the absence of initiator, methyl ketone 2b and phenyl ketone 3 produce radicals resulting from abstraction

  首次研究了自由基引发剂存在下三氟甲基酮（TFMKs）1a-1e与非氟化酮2a-2b的光顺磁共振光谱。通过捕获2-甲基-2-亚硝基丙烷（MNP）和2,4,6-三叔丁基亚硝基苯（TTBNB）作为自旋阱，可以识别出酮辐照后产生的瞬态自由基。由于在N和O原子上有矛盾的反应性，因此TTBNB在产生苯胺和硝氧基自旋加合物的这类过程中是一种强大的，特别有用的自旋阱。在叔丁基过氧化物的存在下，短链TFMK（例如1,1,1-三氟丙酮（1d）和六氟丙酮（1e））可检测到难以捉摸的三氟甲基。相比之下，长链TFMK没有提供线索证明三氟甲基自由基的形成，而是提供了通过将一个α-亚甲基质子抽象为羰基而衍生的自由基的线索。尽管在没有引发剂的情况下TFMK对光降解非常稳定，但甲基酮2b和苯基酮3产生的自由基是由γ-氢抽象为羰基而产生的。

Metallation occurs quantitatively at −78°C and, in contrast to what has been generally recommended, there is no need to add the second equivalent of base, since its presence may be detrimental if other electrophilic

  通过在等摩尔量的叔丁基锂存在下将相应的碘化物金属化，然后与氟代酰化剂反应，可以实现长链三氟甲基酮的直接高效合成。金属化在-78°C下定量发生，与通常所建议的相反，不需要添加第二当量的碱，因为如果分子中存在其他亲电子功能，则其存在可能是有害的。
