The first strategy for bringing about enantioselectiveazlactonedynamickineticresolution to generate orthogonally protected amino acids has been developed. In the presence of a C2‐symmetric squaramide‐based catalyst, benzyl alcohol reacts with novel yet readily prepared tetrachloroisopropoxycarbonyl‐substituted azlactones to generate trapped phthalimide products of significant synthetic interest

The catalytic, alcoholytic kinetic resolution of oxazinones is reported. A novel, stereochemically dense cinchonaalkaloid-basedcatalyst can facilitate the highly enantiodiscriminatory (S up to 101) ring-opening of oxazinones equipped with electrophilic aryl units to generate orthogonally protected β-amino acids for the first time.
