Chelation Controlled Nucleophilic Addition of Tetraoric Acid Dianion to Aldimines: Towards the Stereoselective Construction of b-Amino Alcohols
摘要:
Nucleophilic addition reaction of tetronic acid dianion, derived from tetronic acid with lithium diisopropylamide, to aldimines was found to proceed in a stereoselective manner providing syn adducts predominantly via the six-membered chelation transition states.
