The synthesis of pyridines from readily available α,β-unsaturated oximes and alkynes under mild conditions and low temperatures using Rh(III) catalysis has been developed. It was found that the use of sterically different ligands allows for complementary selectivities to be achieved.
利用Rh(III)催化剂,在温和条件和低温下,通过易得α,β-不饱和肟与炔烃的合成反应,开发了吡啶的合成方法。研究发现,使用空间位阻不同的配体可以实现互补的选择性。
