2-Indolylglycine derivative and its oxygen analogue have been synthesized by Sonogashira coupling followed by cyclization in one pot between 2-iodoheteroarenes and ethynyloxazolidinone where 3-indolylglycine derivative and its oxygen analogue have been synthesized from silylated internal alkyne using Larock’s heteroannulation as the key reaction.
2-吲哚基甘氨酸衍生物及其氧类似物是通过Sonogashira偶联合成的,然后在2-碘杂杂芳烃和乙炔基恶唑烷酮之间的一锅中环化,其中3-吲哚基甘氨酸衍生物及其氧类似物是由甲硅烷基化的内部炔烃合成的,并使用Larock杂环化作为关键反应。
