    • An optically active ester of the formula ##STR1## wherein p is 0 or 1, q is 1 or 2, r is 1 or 2, q+r is 3, and s is 0 or 1. R.sub.1 and R.sub.2 in the above formula are each independently selected from the group consisting of C.sub.6-18 straight chain alkyl and an optically active group of the formula ##STR2## and in which m is 2 to 5, n is 1 or 2, X is hydrogen or chlorine, R.sub.3 is hydrogen or C.sub.1-11 straight chain alkyl, and C.sup.* represents a chiral carbon atom, with the proviso that when n is 1 and X is hydrogen, R.sub.3 is C.sub.1-11 straight chain alkyl. When q is 2 and r is 1 and R.sub.1 is C.sub.6-18 straight chain alkyl, p is 1; on the other hand, when q is 1 and r is 2 and R.sub.2 is an optically active group of the above formula, s is 1. One of R.sub.1 and R.sub.2 is an optically active group of the above formula, and the other of R.sub.1 and R.sub.2 is C.sub.6-18 straight chain alkyl.
    • 式IMA的光学活性酯,其中p为0或1,q为1或2,r为1或2,q + r为3,s为0或1.上式中的R 1和R 2为 各自独立地选自C6-18直链烷基和式IMAMA的光学活性基团,其中m为2至5,n为1或2,X为氢或氯,R3为氢或 C1-11直链烷基,C *表示手性碳原子,条件是当n为1且X为氢时,R 3为C 1-12直链烷基。 当q为2且r为1且R 1为C 6-18直链烷基时,p为1; 另一方面,当q为1且r为2,R2为上式的光学活性基团时,s为1.其中R1和R2为上式的光学活性基团,R1和 R2是C6-18直链烷基。
