  a typical antipsychotic drug (APD) associated with an increased risk of extrapyramidal side effects (EPSs) and hyperprolactinemia relative to atypical APDs such as clozapine. Both drugs are dopamine D2 receptor (D2R) antagonists, with contrasting kinetic profiles. Haloperidol displays fast association/slow dissociation at the D2R, whereas clozapine exhibits relatively slow association/fast dissociation

  氟哌啶醇是一种典型的抗精神病药物（APD），与非典型APD（例如氯氮平）相比，其锥体束外副作用（EPS）和高泌乳素血症的风险增加。两种药物都是多巴胺D 2受体（D 2 R）拮抗剂，具有相反的动力学特征。氟哌啶醇在D 2 R处显示快速缔合/缓慢解离，而氯氮平显示相对较慢的缔合/快速解离。最近，我们提供了证据，从D 2 R缓慢解离可预测高泌乳素血症，而快速结合可预测EPS。不幸的是，氯氮平可引起严重的副作用，而与D 2 R作用无关。我们的结果表明D 2的最佳动力学曲线避免EPS的R拮抗剂APD。为了开始研究该假设，我们进行了氟哌啶醇的结构动力学关系研究，并发现微妙的结构修饰会显着改变结合动力学速率常数，从而提供具有氯氮平样动力学特征的化合物。因此，这些动力学参数的优化可以允许开发基于氟哌啶醇支架的具有改善的副作用特征的新型APD。

  DBU介导的异硫氰酸酯和炔丙醇的5-exo-dig环化反应可形成有价值的杂环化合物。发现异硫氰酸酯的亲核性的不同模式（S-选择性或N-选择性）取决于炔丙醇的取代模式。对末端炔丙醇和异硫氰酸酯进行N-亲核攻击，得到3-取代的4-亚甲基恶唑烷-2-硫酮。相反，观察到内部炔丙醇的独家S亲核环化反应产生（Z）-1,3-氧杂硫醇-2-亚烷基和（Z）-N-（Z）-4-亚乙基-1,3-氧杂硫杂环戊烷-分别来自仲和伯炔丙醇的2-亚烷基。在亚胺基序和烯烃中高Z选择性的形成是这种新方法的亮点，因为在C [双键，在单个系统中，如m-N和C双键的长度，如m-C的长度在合成上是非常具有挑战性的。亚胺和烯烃中的Z-选择性可以分别归因于电子和空间因素。
