An unprecedented formal [3+2] annulation of propargylamides with TMSN3 to deliver functionalized tetrazoles is developed. Oxygen-atom transfer (OAT) from amide group to C[identical with]C bond was realized via a NIS-triggered-cyclization/ring-opening cascade...
开发了空前的炔丙基酰胺与TMSN3进行正式的[3 + 2]环合,以递送官能化的
四唑。通过NIS触发的环化/开环级联反应实现了酰胺基到C [C]键的氧原子转移(OAT)。
