A naphthalene derivative of the formula:
wherein R1 is hydrogen and R2 is lower alkyl or phenyl-lower alkyl; or R' and R2 are combined together to form lower alkylene; X is halogen; and the absolute configuration at the asymmetric carbon atom shown by the asterisk is either (S)-or (R)- configuration, and a method of preparation thereof are disclosed. Said naphthalene derivative is useful as a chiral reagent for determining the optical purity of an optically active compound containing within its molecule at least one functional group selected from hydroxy, amino and imino groups.
式中的萘衍生物:
其中 R1 为氢,R2 为低级烷基或苯基-低级烷基;或 R' 和 R2 结合在一起形成低级亚烷基;X 为卤素;星号所示不对称碳原子的绝对构型为 (S)- 或 (R)- 构型,并公开了其制备方法。所述萘衍生物可用作手性试剂,用于测定分子中含有至少一个选自羟基、氨基和亚氨基的官能团的光学活性化合物的光学纯度。
