CODEN: SYNTBF.Several substances with their cas registry numbers 15097-49-1 and 3908-55-2 may be metioned in this study. ISSN: 0039-7881. DOCUMENT TYPE: Journal CA Section: 27 (Heterocyclic Compounds (One Hetero Atom)) 1,3-Dimethylcyclohepta[c]pyrrol-6(2H)-one was chlorinated with (COCl)2 and treated with LiClO4 to give I.HClO4 (R = Cl) (II). This was treated with Me3SiNR21 [R1 = Me; R21 = (CH2)5, (CH2)6, O(CH2CH2)2] to give I.HClO4 (R = NR21), which gave the free bases on treatment with Me3COK. II reacted with Me3SiSMe to give I (R = MeS). .

Intermolecular versus intramolecular hydrogen-bonding competition in the complexation of cyclitols by a twisted polyaza cleft: Intermolecular versus intramolecular hydrogen-bonding competition in the complexation of cyclitols by a twisted polyaza cleft. Huang, Chia Yu; Cabell, Larry A.; Lynch, Vince; Anslyn, Eric V.Several substances are used for example 15097-49-1 and 138722-51-7 which are their cas registry numbers. (Dep. Chem. Biochem., Univ. Texas, Austin, TX 78712, USA). J. Am. Chem. Soc., 114(5), 1900-1 (English) 1992. CODEN: JACSAT. ISSN: 0002-7863. DOCUMENT TYPE: Journal CA Section: 33 (Carbohydrates) The synthesis of a twisted polyaza cleft I designed to bind a 1,2,3-triol moiety of monosaccharides, and the binding consts. with various cyclitols is presented. The binding consts. obtained are lower than would be expected compared to similar complexes with the same no. of hydrogen bonds and secondary hydrogen bonds. Trans hydroxyl stereochem. in the cyclitols yields higher binding consts. than cis stereochem. Mol. dynamics and mechanics, along with IR studies, and a crystal structure of I indicate that intramol. hydrogen bonds control the selectivity and strength of complexation. Thus, hosts designed to bind saccharides in aprotic low dielec. solvents need to effectively compete with the intramol. hydrogen bonds in order to achieve large assocn. consts. .
