    • The invention provides salts of formula (I) wherein X is a basic counterion selected from a group I or group II metal and a primary, secondary or tertiary amine; n is 0, 1 or 2; and R1, R1a, R2, R2a, R3, R3a, R4 and R4a are independently selected from H and C1-C6 alkyl, or R1 and R2 or R2 and R3 are taken together to form a C3-C7 cycloalkyl ring, which is optionally substituted with one or two substituents selected from C1-C6 alkyl, which are useful as intermediates in the preparation of cyclic and bicyclic amino acids. Processes for the preparation of the final products and for the conversion of the compounds of formula (I) to amino acids are included.
    • 本发明提供了式(I)的盐,其中X是选自I或II族金属和伯,仲或叔胺的碱性抗衡离子; n为0,1或2; R 1,R 2,R 2,R 2,R 3,R 3, R 4a,R 4和R 4a独立地选自H和C 1 -C 3烷基, 6个或多个R 1,R 2,R 2,R 2,R 3和R 3连接在一起 以形成C 3 -C 7 - 环烷基环,其任选被一个或两个选自C 1 -C 7 - 其可用作制备环状和双环氨基酸的中间体。 包括制备最终产物和将式(I)化合物转化为氨基酸的方法。
