  4取代3羧基吡唑的制备

  摘要：

  研究了报道的三种合成方法的制备范围，这些方法用于制备一系列在4位具有取代基的3-吡唑羧酸酯。第一种是基于甲基吡唑的高锰酸钾氧化。第二步开始于DMF二甲基乙缩醛和丙酮酸乙酯之间的缩合，然后加入盐酸肼。最后一种利用重氮甲烷在丙烯酸酯上的环加成反应，然后将基于溴的氧化重排成4-取代的3-吡唑酯。

• Lead optimization of the VU0486321 series of mGlu 1 PAMs. Part 2: SAR of alternative 3-methyl heterocycles and progress towards an in vivo tool

  This Letter describes the further lead optimization of the VU0486321 series of mGlu1 positive allosteric modulators (PAMs), driven by recent genetic data linking loss of function GRM1 to schizophrenia. Steep and caveat-laden SAR plagues the series, but ultimately potent mGlu1 PAMs (EC50s ∼5 nM) have resulted with good DMPK properties (low intrinsic clearance, clean CYP profile, modest Fu) and CNS penetration

  这封信描述了VU0486321系列mGlu 1阳性变构调节剂（PAM）的进一步前导优化，这是由将功能GRM1的丧失与精神分裂症联系起来的最新遗传数据驱动的。陡峭和饱满的SAR困扰着该系列，但最终有效的mGlu 1 PAM（EC 50 s〜5 nM）产生了良好的DMPK特性（低内在清除率，干净的CYP曲线，适度的F u）和CNS渗透率（K p s 0.25–0.97），以及相对于mGlu 4和mGlu 5高达450倍以上的选择性。
