  镁/甲醇：一种化学选择性还原嘧啶-2（1 H）-ones的有效还原剂

  摘要：

  甲醇中的镁是化学选择性还原嘧啶2（1 H）-ones的有效试剂。其他可还原的官能团，例如烯胺酯和乌里多羰基的酯和烯烃，不受影响。这构成了通过嘧啶-2（1 H）-one的还原形成Biginelli 3,4-dihydropyrimidin-2（1 H）one的第一个例子。

  The present disclosure relates to bifunctional compounds, which find utility to degrade and (inhibit) Androgen Receptor. In particular, the present disclosure is directed to compounds, which contain on one end a cereblon ligand which binds to the E3 ubiquitin ligase and on the other end a moiety which binds Androgen Receptor, such that Androgen Receptor is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of Androgen Receptor. The present disclosure exhibits a broad range of pharmacological activities associated with compounds according to the present disclosure, consistent with the degradation/inhibition of Androgen Receptor.
