    摘要:
    的可靠的三步合成邻-取代的4-吡唑基-2-乙基胺从吡唑甲基酮开始和ñ -叔描述-butanesulfinylamine。强烈需要进行脱水的条件来形成Ñ -叔-butanesulfinyl酮亚胺,但是这些中间体是稳定的,以含水后处理和色谱法。的还原Ñ -叔在THF中与L-selectride®或Super-hydride®一起使用-丁烷亚磺酰基酮亚胺可提供优异的亚磺酰胺收率和非对映选择性,并用HCl甲醇转化为手性胺。这些研究中的4-吡唑基-2-乙基胺是药物化学家的有吸引力的构成部分,因为它们显示出低分子量和低计算辛醇-水分配系数(cLog P值),同时破坏了具有三维特征的平面度。例如,胺产物被用于人类瞬时受体电位类香草素1(TRPV1 / VR1)的结构活性研究。

  • Fused heterocyclic compounds and pharmaceutical applications thereof

    公开(公告)日:2001-02-13
    The present invention relates to a fused heterocyclic compound of the formula (I) wherein each symbol is as defined in the specification, an optical isomer thereof, a pharmaceutically acceptable salt thereof, a pharmaceutical composition containing a compound of the formula (I), an optical isomer thereof or a pharmaceutically acceptable salt thereof, and a pharmaceutically acceptable additive, and a medicament containing a compound of the formula (I), an optical isomer thereof or a pharmaceutically acceptable salt thereof. The compound of the present invention is a useful antipsychotic agent effective not only for positive symptoms centering on hallucination and delusion characteristic of the acute stage of schizophrenia, but also negative symptoms of apathy, abulia and autism. The inventive compound is expected to make a highly safe antipsychotic agent associated with less side effects, such as extrapyramidal symptoms and endocrine disturbance, which are observed when a conventional antipsychotic agent having a D2 receptor blocking action is administered. Therefore, the inventive compound can be used as a therapeutic agent for the diseases such as schizophrenia.
    本发明涉及一种融合杂环化合物,其化学式为(I),其中每个符号如规范中定义的一个光学异构体,一个药学上可接受的盐,含有化合物(I)、其光学异构体或药学上可接受的盐的药物组合物,以及药学上可接受的添加剂和含有化合物(I)、其光学异构体或药学上可接受的盐的药物。本发明化合物是一种有用的抗精神病药物,不仅对于中心于幻觉和妄想的阳性症状,也对于无动力、无意志和自闭症等阴性症状有效。本发明化合物预计成为一种高度安全的抗精神病药物,与传统的具有D2受体阻滞作用的抗精神病药物相比,其副作用较少,如锥体外系症状和内分泌紊乱。因此,本发明化合物可用作治疗精神分裂症等疾病的治疗剂。

    A reliable three-step synthesis of ortho-substituted 4-pyrazolyl-2-ethylamines starting from a pyrazole methyl ketone and N-tert-butanesulfinylamine is described. Strongly dehydrating conditions were required to form the N-tert-butanesulfinyl ketimines, but these intermediates were stable to aqueous work-up and chromatography.
