Aziridines are very useful intermediates for the synthesis of numerous nitrogen-containing biologically active compounds. 1 Therefore, nucleophilic ring-opening of aziridines by various approaches has been widely examined and developed. 2 Among these approaches, the ring-opening reaction using silylated nucleophiles, such as silyl cyanide, azide or halides, is important to produce highly functionalized compounds. Therefore, the catalytic ring-opening reaction with silylated ...
