制备方法与用途

化学性质：闪点为93℃。

用途：用作农药中间体。

生产方法：3-氯-4-甲基苯胺经光气化而得到3-氯-4-甲苯异氰酸酯。具体步骤是将3-氯-4-甲基苯胺溶解在甲苯（或氯苯）中，使其浓度控制在150-170g/L。在0℃以下的低温条件下，通入光气，光气体积约为胺的2.5倍（摩尔比）。随后缓缓升温至70-80℃，反应1-2小时后继续加热到100-105℃进行赶气处理，即可得到3-氯-4-甲苯异氰酸酯溶液。

  Phenotypic Optimization of Urea–Thiophene Carboxamides To Yield Potent, Well Tolerated, and Orally Active Protective Agents against Aminoglycoside-Induced Hearing Loss

  摘要：

  Hearing loss is a major public health concern with no pharmaceutical intervention for hearing protection or restoration. Using zebrafish neuromast hair cells, a robust model for mammalian auditory and vestibular hair cells, we identified a ureathiophene carboxamide, 1 (ORC-001), as protective against aminoglycoside antibiotic (AGA)-induced hair cell death. The 50% protection (HC50) concentration conferred by 1 is 3.2 mu M with protection against 200 mu M neomycin approaching 100%. Compound 1 was sufficiently safe and drug-like to validate otoprotection in an in vivo rat hearing loss model. We explored the structureactivity relationship (SAR) of this compound series to improve otoprotective potency, improve pharmacokinetic properties and eliminate off-target activity. We present the optimization of 1 to yield 90 (ORC-13661). Compound 90 protects mechanosensory hair cells with HC50 of 120 nM and demonstrates 100% protection in the zebrafish assay and superior physiochemical, pharmacokinetic, and toxicologic properties, as well as complete in vivo protection in rats.

• Functionalities tuned enantioselectivity of phenylcarbamate cyclodextrin clicked chiral stationary phases in HPLC

  日期：2017.9

  phenylcarbamate cyclodextrin (CD) clicked chiral stationary phases (CSPs). A comparison study is herein reported for per(4‐chloro‐3‐methyl)phenylcarbamate and per(2‐chloro‐5‐methyl)phenylcarbamate β‐CD clicked CSPs (i.e., CCC4M3‐CSP and CCC2M5‐CSP). The enantioselectivity dependence on column temperature was studied in both normal‐phase and reversed‐phase mode high performance liquid chromatography

  混合的氯官能团和甲基官能团可以极大地调节苯基氨基甲酸酯环糊精（CD）咔哒手性固定相（CSP）的对映选择性。本文报道了对（4-氯-3-甲基）苯基氨基甲酸酯和（2-氯-5-甲基）苯基氨基甲酸酯β-CD裂解的CSP（即CCC4M3-CSP和CCC2M5-CSP）的比较研究。在正相和反相模式高效液相色谱（HPLC）中均研究了对映选择性对柱温的依赖性。热力学研究表明，CCC4M3-CSP与手性溶质之间可形成更强的分子间相互作用，以驱动手性分离。通过在HPLC中对17种模型外消旋物进行对映分离，进一步证明了CCC4M3-CSP的对映选择性更高。
