• Enantioselective Chemoenzymatic Synthesis of the S-Enantiomer of the Systemic Fungicide Fenpropimorph

  日期：1995.11

  Chemoenzymatic synthesis of the S-(-)-enantiomer of fenpropimorph (S)-1 in high optical and chemical purity is described. One feature of this process entails the enantioselective acetylation of prochiral 1,3-propanediol 4 by Pseudomonas sp. lipases, and subsequent transformation of the monoacetate (R)-5 into the final product by the selected order of transformations that comprise; chlorination or tosylation under non-racemizing conditions, hydrogenolysis of the resulting chloromethyl or tosyl group in (+)-6 and (+)-8, second chlorination of (-)-9, and alkylation of cis-3,5-dimethylmorpholine by 1-chloropropane derivative (+)-10. This sequence of reactions affords (S)-1, the more active enantiomer in the commercialized racemic mixture with systemic fungicidal activity.

  本研究介绍了高光学纯度和化学纯度的芬普吗啉（S）-1 的 S-(-)-对映体的化学合成。该工艺的一个特点是通过假单胞菌（Pseudomonas sp.该工艺的特点之一是利用假单胞菌脂肪酶对 1,3-丙二醇 4 的手性进行对映体选择性乙酰化，然后通过选定的转化顺序将单乙酸酯 (R)-5 转化为最终产品，这些转化顺序包括：在非梯度化条件下进行氯化或甲苯磺酰化反应，对 (+)-6 和 (+)-8 中产生的氯甲基或甲苯磺酰基进行氢解反应，对 (-)-9 进行第二次氯化反应，以及用 1-氯丙烷衍生物 (+)-10 对顺式-3,5-二甲基吗啉进行烷基化反应。通过这一系列反应，可得到(S)-1，它是商品化外消旋混合物中活性更强的对映体，具有系统杀菌活性。
• N-(3-acyloxy-2-benzylpropyl)-N′-(4-hydroxy-3-methoxybenzyl)thiourea derivatives as potent vanilloid receptor agonists and analgesics

  A series of N-(3-acyloxy-2-benzylpropyl)-N'-(4-hydroxy-3-methoxybenzyl)thioura derivatives were investigated as vanilloid receptor ligands in an effort to discover a novel class of analgesics. The proposed pharmacophore model of resiniferatoxin, which includes the C-20-homovanillic moiety, the C-3-carbonyl and the orthoester phenyl ring as key pharmacophoric groups, was utilized as a guide for drug design. The compounds were synthesized after several steps from diethylmalonate and evaluated in vitro in a receptor binding assay and in a capsaicin-activated channel assay. Additional evaluation of analgesic activity, anti-inflammatory activity and pungency was conducted in animal models by the writhing test, the ear edema assay, and the eye-wiping test, respectively. Among the new compounds, 23 and 28 were found to be the most potent receptor agonists of the series with K-i values of 19 nM and 11 nM, respectively. Their strong in vitro potencies were also reflected by an excellent analgesic profile in animal tests with ED50 values of 0.5 mug/kg for 23 and 1.0 mug/kg for 28. Relative to capsaicin these compounds appear to be ca. 600 and 300 times more potent. Both 23 and 28 were found to be less pungent than capsaicin based on the eye-wiping test. However, the compounds did not show significant anti-inflammatory activity. A molecular modeling study comparing the energy-minimized structures of resiniferatoxin and 35 demonstrated a good correlation in the spatial disposition of the corresponding key pharmacophores. The thioureas described in this investigation, which were designed as simplified resiniferatoxin surrogates, represent a novel class of potent vanilloid receptor agonists endowed with potent analgesic activity and reduced pungency.
