Highly potent and selective small molecule neuropeptideYY2receptorantagonists are reported. The systematic SAR exploration of a hit molecule N-(4-ethoxyphenyl)-4-[hydroxy(diphenyl)methyl]piperidine-1-carbothioamide, identified from HTS, led to the discovery of highly potent NPY Y2antagonists 16 (CYM 9484) and 54 (CYM 9552) with IC50 values of 19 nM and 12 nM respectively.

Oxoammonium salt-promoted diverse functionalization of saturated cyclic amines with different dinucleophiles under mild conditions is presented. Specifically, when thiocyanate is used as a 1,3-dinucleophile, hexahydrothiazolo[4,5-b]pyridin-2(3H)-one derivatives are formed via the formation of the β-TEMPO-tethered cyclic iminium ion as a key intermediate. By contrast, when benzene-1,2-diamine is used
介绍了在温和条件下,氧铵盐促进饱和环胺与不同亲核试剂的不同功能化。具体而言,当硫氰酸盐用作 1,3-二亲核试剂时,通过形成 β-TEMPO-系链亚胺离子作为关键,形成六氢噻唑并[4,5- b ]吡啶-2(3 H )-酮衍生物中间的。相比之下,当苯-1,2-二胺用作 1,4-二亲核试剂时,2-烷基喹喔啉衍生物是通过生成 β-氧代环状亚胺离子作为关键中间体得到的。此外,2-烷基喹喔啉的有用性通过它们容易转化为N2来展示-(2-oxo-2-(quinoxalin-2-yl)ethyl)nitroniamides 具有合成有用的 N-NO 部分和羰基。

operationally simple and practical protocol to access N-CF2H amides and related carbonyl derivatives was developed. The protocol utilizes a one-pot conversion of thioformamides via desulfurization-fluorination and acylation, providing N-difluoromethylcarbamoyl fluoride that can be further diversified to a diversity of N-CF2H carbonyl compounds including amides, carbamates, ureas, thiocarbamates, and selenocarbamates
