We herein report an efficient and systematic synthesis of 1-pyrrolines from cyclobutyl azides under thermal and neutral conditions. The reaction proceeded without any additional reagents, and nitrogen was generated as the sole by-product. Furthermore, the generated 1-pyrrolines could be continuously transformed into pyrroles, N-Boc-amines, and oxaziridines in an one-pot manner.
我们在此报告了在热和中性条件下从环丁基叠氮化物有效和系统地合成 1-吡咯啉。反应在没有任何额外试剂的情况下进行,生成的唯一副产物是氮气。此外,生成的 1-吡咯啉可以以一锅法连续转化为吡咯、N -Boc-胺和氧氮丙啶。
