Asymmetric synthesis of optically active cis-3-acetoxy-5-hydroxycyclopent-1-ene: Asymmetric synthesis of optically active cis-3-acetoxy-5-hydroxycyclopent-1-ene. Takano, Seiichi; Ogasahara, Kunio; Tanigawa, Keizo (Japan ). Japan. Kokai JP 53005140 18 Jan 1978 Showa,3 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C07C069-16. APPLICATION: JP 76-77925 2 Jul 1976. DOCUMENT TYPE: Patent CA Section: 16 (Fermentations) A sterilized fermn. broth of meat ext. 5, peptone 15, NaCl 5, K2HPO4 5, agar 3, and glucose 1 g in 100 mL H2O was inoculated with Bacillus subtilis niger and shaken 3 days at 28°. To this broth 1.84 g cis-3,5-diacetoxycyclopent-1-ene (I) [54664-61-8] was added, and the whole was shaken 15 h at 28° to give 1.84 g crude optically active cis-3-acetoxy-5-hydroxycyclopentene (II) [60410-16-4], which was purified by high vacuum distn.

Extending the applicability of esterases of low enantioselectivity in asymmetric synthesis: Extending the applicability of esterases of low enantioselectivity in asymmetric synthesis. Wang, Yi Fong; Chen, Ching Shih; Girdaukas, Gary; Sih, Charles J. (Sch. Pharm., Univ. Wisconsin, Madison, WI 53706, USA). Ciba Found. Symp., 111(Enzymes Org. Synth.In this article, certain chemicals are used. One of their cas registry numbers is 54664-61-8 ), 128-45 (English) 1985. CODEN: CIBSB4. ISSN: 0300-5208. DOCUMENT TYPE: Journal CA Section: 9 (Biochemical Methods) Section cross-reference(s): 7, 63 A strategy for expanding the applicability of esterases of low enantioselectivity for asym. synthesis is described. This concept is generally applicable to biochem. processes involving enantiotopic group differentiation. Quant. expressions were derived to permit the prediction of enantiomeric excess and the optimization of optical and chem. yields. As an example, meso-diester, 1,5-diacetoxy-cis-2,4-dimethylpentane was used as a model substrate for incubation with pig pancreatic lipase and pig liver esterase. .
