  N,N'-(phenylene)dioxamic acids and their esters as antiallergy agents

  摘要：

  A series of dialkyl N,N'-(m-phenylene)dioxamates was synthesized by treatment of the requisite m-phenylenediamines with an alkyloxalyl chloride in the presence of triethylamine. Hydrolysis with sodium hydroxide solution gave the corresponding N,N'-(m-phenylene)dioxamic acids. Several N,N'-(p-phenylene)dioxamic acids were synthesized also in the same manner starting with the requisite p-phenylenediamines. These compounds were tested in the rat passive cutaneous anaphylaxis (PCA) assay. When tested iv, activity was found in the N,N'-(m-phenylene) dioxamic acids up to 2500 times that shown by disodium cromoglycate [50% inhibition at 0.001 mg/kg for N,N'-(2-chloro-5-cyano-m-phenylene)dioxamic acid (compound 61)]. Oral activity was seen in this series of compounds with duration of activity up to 120 min. Oral activity was detected in diethyl N,N'-(2-chloro-5-cyano-m-phenylene)dioxamate (compound 38) at levels of drug as low as 0.1 mg/kg.

  of over 20 000. The reaction of aniline with 4-X-2,6-dinitrochlorobenzenes is subject to considerably larger para-substituent effects than the corresponding reactions with N-methylaniline. These results are interpreted in terms of two effects: (i) A primary steric effect, which renders the approach of N-methylaniline to the substrate difficult. (ii) A shift towards earlier, more reactant-like transition

  苯胺和N-甲基苯胺与各种取代的硝基氯苯在乙腈中的S N Ar反应动力学表明，中间体σ-络合物的形成决定了速率。苯胺和N-甲基苯胺反应的速率常数之比（k A / k M）随着6位取代基尺寸的增加而增加。用苦基氯ķ甲/ ķ中号达到的超过一个值20000 。苯胺与4-X-2,6- dinitrochlorobenzenes反应受到相当大的第-取代基的作用要比与N-甲基苯胺的相应反应要大。这些结果可以用两种效应来解释：（i）主要的空间效应，这使N-甲基苯胺难以接近底物。（ii）由主要的空间效应引起的向更早的，更像反应物的过渡态结构的转变。在早期过渡态中，预计衬底中吸电子替代物的活化能力相对较小。缓慢的N-甲基苯胺反应的早期过渡态和快速苯胺反应的晚期过渡态明显与基于Hammond假设的预期相矛盾。
