A highly facile, efficient, and enantioselectivebromolactamization of olefinic amides was effected by a carbamate catalyst and ethanol additive. The amide substrates underwent N‐cyclization predominantly to give a diverse range of enantioenriched bromolactam products containing up to two stereogenic centers.
