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.
可以通过改变手性合成子的1-(R)(或1-(S))手性合成子1-(R)(或1-(S))以光学纯净的形式制备两种不同类型的环状α-氨基酸,即环烷基甘氨酸和N-杂环α-氨基酸。阴离子形成所需的碱类型。杂环中间体3的详述提供了α,β-不饱和的N-杂环α-氨基酸。
