Abstract
A simple strategy for the synthesis of highly substituted 2-imidazolines starting from terminal alkynes, sulfonyl azides, and N-unsubstituted aziridines via two steps with high regioselectivity is described.
Key words
2-imidazolines - sulfonyl azides - N-unsubstituted aziridines - three-component coupling - isomerization
