NMR study of 9,9'-(alkane-a,w-diyl)diadenine

NMR study of 9,9'-(alkane-a,w-diyl)diadenine. Itahara, Toshio (Inst. Chem., Kagoshima Univ., Kagoshima 890, Japan). Journal of the Chemical Society, Perkin Transactions 2: Physical Organic Chemistry, (12), 2695-2700 (English) 1996 Royal Society of Chemistry. CODEN: JCPKBH. ISSN: 0300-9580. DOCUMENT TYPE: Journal CA Section: 33 (Carbohydrates) The relationship between NMR chem shifts of adenine ring protons of low concns. of 9,9'-(alkane-a,w-diyl)diadenine I (n = 1-12) and the length of the polymethylene chains has been investigated in buffer solns. at pD 1. 33147-26-1 and 4549-33-1 are cas registry numbers of chemicals which are used as reagents here.0, 7.0 and 13.0 and in org. solvents such as CD3OD, (CF3)2CDOD, [2H6]dimethyl sulfoxide and CF3COOD. The chem. shifts were compared with those of 9-(w-bromoalkyl)adenine. .
