1,2:5,6-Di-O-isopropylidene-3,4-bis-O-(4-vinylbenzoyl)-D-mannitol (1a) and -D-glucitol (1b) with styrene (St) were polymerized using AIBN in toluene at 60 degrees C to yield copolymers (2a and 2b, respectively) consisting essentially of the cyclic repeating and styrene units. In order to confirm asymmetric induction in 2, the removal of the template from 2 was carried out using KOH in aqueous MeOH, and then the resulting hydrolyzed copolymer was treated with diazomethane for conversion into poly[(methyl 4-vinylbenzoate)-co-styrene] (3). Copolymers 2a and 2b showed a negative specific rotation, whereas a positive rotation was observed for 3a and 3b. The CD spectrum of la exhibited a negative Cotton effect at 300.0 nn and a positive one at 267.3 nm as well as a negative exciton coupling of Ib. According to the exciton chirality method, la and Ib had a negative chirality and its benzoate chromophores, the two 4-vinylbenzoyl groups, were twisted counterclockwise. On the other hand, the CD spectrum of 3a (1a/St = 0.30/0.70) and 3b (1b/St = 0.27/0.73) showed a split Cotton effect with a positive one at 254.9 nm and a negative one at 237.1 nm for 3a and with a positive Cotton effect at 254.7 nm and a negative one at 232.7 nm for 3b. This result indicated that 3 had a positive chirality in which two 4-vinylbenzoyl groups were twisted clockwise, i.e., the vicinal (methyl 4-vinylbenzoate) groups in the main chain were an (S,S)-configuration.
