Abstract
The Barbier approach was used for diastereoselective formation of allylamino acid derivatives. The stereochemical models for nucleophilic addition to N -tosylimines bearing various chiral auxiliaries such as (2R )-bornano-10,2-sultam, (R )-8-phenylmenthol, and 10-N ,N -dicyclohexylsulfamoyl-(R )-isoborneol are proposed.
Key words
chiral auxiliaries - imines - nucleophilic additions - organometallic reagents - stereoselectivity
