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

The molecular ion 1 of N -( n -propoxy)benzaldimine I rearranges by an 1,5-H-shift to the δ-distonic ion 2 which subsequently cyclizes to the α-distonic ion 3 . Homolytic cleavage of the N–O bond in 3 results in the δ-distonic ion 4 which expels CH2O leading to the β-distonic ion 5 . Ion 5 is also formed from the molecular ions of tetrahydrooxazines II and III and from M+• of phenylazetidine IVa
分子离子 1 的 ñ - ( ñ -丙氧基)benzaldimine 我 由1,5- H-转移到δ-distonic离子重新排列 2 ,其随后环化成α-distonic离子 3 。N-O键在 3 中的均质裂解 导致δ-distonic离子 4 排出CH 2 O导致β-distonic离子 5 。离子 5 也由四氢恶嗪 II 和 III 的分子离子 以及 苯基 氮杂环丁烷IVa的 M +•形成 。在随后的步骤中,离子 5 环 化为 N- 质子化的3,4-二氢异喹啉鎓离子 6 。描述了 II – IV 及其衍生物的合成 。
