TBSOTf, underwent the RCM reaction in the presence of Grubbs catalyst to give oxazoloazepines or oxazoloazecines, which were readily converted into N-unsubstituted seven-membered or eight-membered lactams by the reductive treatment.
由仲O-酰基扁桃酰胺经TBSOTf处理制得的氧恶唑烷酮,在Grubbs催化剂存在下进行RCM反应,得到恶唑并ze庚因或恶唑并ze嗪,它们易于通过还原反应转化为N-未取代的七元或八元内酰胺。治疗。
