摘要

Lateral metallation at C-2 (α) of 1-tert-butoxycarbonyl-2-methyl-2-imidazoline followed by reaction with a range of C-electrophiles and deprotection with TFA reliably affords N (1)- unsubstituted 2-substituted 2-imidazolines; P-or Se-electrophiles lead to 2-alkenyl-2- imidazolines via Wadsworth–Emmons or selenoxide elimination protocols.
