Abstract
A catalyst-free and atom-economical [4 + 3] cycloaddition of azadienes with C,N-cyclic azomethine imines has been developed, providing an efficient and environmentally benign access to 1,2,4-triazepines with high diastereoselectivities and yields. This reaction can be performed in 2-methyltetrahydrofuran under mild conditions smoothly.
