We developed a nitroxyl-catalyzed bromoesterification of alkenes with bromo reagents, which includes a six-membered ring bromolactonization of alkenyl carboxylic acids catalyzed by AZADO as the nitroxyl radical catalyst, and an intermolecular bromoesterification of alkenes with carboxylic acids using NMO as the N-oxide catalyst. We also accomplished a remote diastereoselective bromohydroxylation via an AZADO-catalyzed six-membered ring bromolactonization and a subsequent ring cleavage reaction with alkylamines to furnish ?-bromo-δ-hydroxy amides with high diastereoselectivity.

Starting with chiral non-racemic esters of lactic acid 7 and mandelic 8, respectively, chiral nitrones 4 have been prepared.They spontaneously undergo an intramolecular cycloaddition which proceeds with asymmetric induction by the chiral center yielding e
