Optically active 2-methylene-4-substituted-1,3-dioxolane homopolymers: Optically active 2-methylene-4-substituted-1,3-dioxolane homopolymers. Endo, Takeshi (Kyowa Hakko Kogyo Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 61166829 A2 28 Jul 1986 Showa, 4 pp. (Japan) CODEN: JKXXAF. CLASS: ICM: C08G063-06. APPLICATION: JP 84-166000 8 Aug 1984. DOCUMENT TYPE: Patent CA Section: 35 (Chemistry of Synthetic High Polymers) Section cross-reference(s): 28 The title polymers (CH2CO2CH2CHR)n (I) [R = (substituted) Ph or naphthyl; n = 55-195) are prepd. and are potentially metabolizable.There are some reagents with their cas registry numbers 103637-53-2 and 97-97-2 are used in this study. Thus, a mixt. of 0.4 mol ClCH2CH(OMe)2, 0.4 mol l-styrene glycol, and 0.5 g Dowex 50 (H+) was heated, filtered, and distd. to give 2-chloromethyl-4-phenyl-1,3-dioxolane (II) in 64.8% yield. A soln. of 0.076 mol II in 40 mL tert-BuOH was added slowly to 110 mL tert-BuOH contg. 0.09 mol tert-BuOK and refluxed 24 h to give optically active 2-methylene-4-phenyl-1,3-dioxolane (III) in 37% yield. A mixt. of 0.8 g III and 14 mg tert-Bu2O2 was heated 41 h at 120° to prep. an optically active polymer I (R= Ph) in 50.8% yield. .

2-Chloromethyl-1,3-dioxacyclohept-5-ene: 2-Chloromethyl-1,3-dioxacyclohept-5-ene. (Toa Gosei Chemical Industry Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 58134087 A2 10 Aug 1983 Showa, 4 pp. (Japanese).There are some reagents with their cas registry numbers 28546-87-4 and 97-97-2 are used in this study. (Japan). CODEN: JKXXAF. CLASS: IC: C07D321-06; C08F016-38. APPLICATION: JP 82-14808 3 Feb 1982. DOCUMENT TYPE: Patent CA Section: 28 (Heterocyclic Compounds (More Than One Hetero Atom)) Title compd. (I) was prepd. by reaction of ClCH2CH(OMe)2 (II) with HOCH2CH:CHCH2OH (III) in the presence of Amberlyst-15. Thus, heating a mixt. of II 199.3, III 141, and Amberlyst-15 2 g 5 h at 110-115° gave 55% I. .
