  铜催化的[2 + 2 + 2]模块化合成多取代的吡啶：腈与乙烯基碘鎓盐的烯基化

  摘要：

  通过铜催化已经实现了具有优异的区域选择性的多取代吡啶的[2 + 2 + 2]模块化合成，其中涉及三个不同的组分：乙烯基碘鎓盐，腈和炔烃。反应通过腈与乙烯基碘鎓盐的烯基化而容易地形成氮杂-丁二烯基中间体。此外，反应中的炔烃被扩展为烯烃，这是炔烃的成本和相对稀缺性的优点。

  DOI：10.1021/acs.orglett.8b02703

  日期：2018.11.2

  modular and selective synthesis of mono-, di-, tri-, tetra-, and pentasubstituted pyridines is reported. Hydroamination of alkynes with N-silylamine using a bis(amidate)bis(amido)titanium(IV) precatalyst furnishes the regioselective formation of N-silylenamines. Addition of α,β-unsaturated carbonyls to the crude mixtures followed by oxidation affords 47 examples of pyridines in yields of up to 96%

  报道了单，二，三，四和五取代的吡啶的模块化和选择性合成。与炔烃的加氢胺化ñ使用双-silylamine（酰胺化）双（酰氨基）钛（IV）预催化剂配料的区域选择性形成Ñ -silylenamines。将α，β-不饱和羰基加到粗混合物中，然后氧化，得到47个吡啶实例，产率高达96％。该合成途径允许使用该一锅法方案合成包含可变取代模式的各种吡啶，包括药学上相关的2,4,5-三取代的吡啶。
