Abstract
Two different types of cyclic α-amino acids, cycloalkylglycines and N-heterocyclic α-amino acids, were prepared in optically pure form from the same chiral synthon 1-(R) (or 1-(S)) simply by altering the quantity or type of base required for anion formation. Elaboration of the heterocyclic intermediate 3 provided α,β-unsaturated N-heterocyclic α-amino acids.
