A formal [3 + 3] cyclization reaction of diaziridines and quinones has been developed offering 1,3,4-oxadiazinanes in generally high yields (up to 96%). The reaction was catalyzed by Sc(OTf)3 with a large substrate scope for both diaziridines and quinones. The synergistic activation of 1,3-dipolar diaziridines and the dipolar quinones was found to be essential to enable this reaction.
已开发出正式的重氮丙啶和醌的[3 + 3]环化反应,可提供1,3,4-恶二嗪并通常以高收率(高达96%)提供。该反应由Sc(OTf)3催化,对于二氮丙啶和醌均具有较大的底物范围。发现1,3-偶极二氮丙啶和偶极醌的协同活化对于实现该反应是必不可少的。
