摘要
Transesterification reaction of 0.25 M thymidine with 1 M divinyladipate in dimethylformamide (DMF) was catalyzed by an alkaline protease (5 mg ml−1) from Streptomyces sp. (20 units mg−1 min) at 30 °C for 7 days to give 5′-O-vinyladipoyl thymidine (yield 77%) without formation of any by-products. Poly(vinyl alcohol) containing thymidine branches could be obtained by its free-radical polymerization.
