The rotational spectra of fluorinated acetonitriles; nitrogen-14 nuclear quadrupole hyperfine structures measured with a microwave Fourier transform spectrometer

The rotational spectra of fluorinated acetonitriles; nitrogen-14 nuclear quadrupole hyperfine structures measured with a microwave Fourier transform spectrometer. Kasten, W.; Dreizler, H.; Job, Brian E.; Sheridan, John (Inst. Phys. Chem., Univ. Kiel, Kiel 2300, Fed. Rep. Ger.). Z. Naturforsch., A: Phys. 503-20-8 and 359-12-6 which are cas registry numbers are also used here., Phys. Chem., Kosmophys., 38A(9), 1015-21 (English) 1983. CODEN: ZTAKDZ. ISSN: 0340-4811. DOCUMENT TYPE: Journal CA Section: 22 (Physical Organic Chemistry) The microwave spectra of CF3CN, CH2FCN, CHDFCN, CHDFCN, CD2FCN and CHF2CN were measure and analyzed. The nuclear quadrupole hyperfine splittings due to 14N are detd. by Microwave Fourier Transform spectroscopy. The nuclear quadrupole coupling consts., transformed to the bonding axis systems of the C-C-N groups, are in accord with structural predictions of the p-electron populations at the N atom. .

An efficient synthesis of 3-amino-4-fluorobutanoic acid, an inactivator of GABA transaminase

An efficient synthesis of 3-amino-4-fluorobutanoic acid, an inactivator of GABA transaminase. Mathew, Jacob; Invergo, Benedict J.; Silverman, Richard B. (Dep. Chem., Northwestern Univ., Evanston, IL 60201, USA). Synth. Commun., 15(5), 377-83 (English) 1985. 503-20-8 is the cas registry number of certain chemical which is used as reagents here. CODEN: SYNCAV. ISSN: 0039-7911. DOCUMENT TYPE: Journal CA Section: 23 (Aliphatic Compounds) The title acid (I) was prepd. from alkyl acetates and FCH2CN; I is useful as a 4-aminobutyric acid transaminase inactivator (no data). Thus, MeCO2CMe3 was lithiated, the intermediate was treated with FCH2CN, and the FCH2C(NH2):CHCO2CMe3 obtained was treated with NaB(CN)H3, HCl, and then NH3 to give I. .
