Synthesis of Cyclobutane Nucleosides

Nucleosides, Nucleotides and Nucleic Acids, 2011
2-(6-Chloropurinyl)-3-benzoyloxymethylcyclobutanone can be prepared by reaction of 6-chloropurine with 3-benzoyloxymethyl-2-bromocyclobutanone. The N-alkylation gave both N-9 and N-7 regioisomers. Both regioisomers upon hydride reduction followed by aminolysis gave the corresponding adenine nucleoside analogues.

Cyclobutanes in Catalysis

Angewandte Chemie International Edition, 2011
AbstractThe exploitation of ring strain as a driving force to facilitate chemical reactions is a well‐appreciated principle in organic chemistry. The most prominent and most frequently used compound classes in this respect are oxiranes and cyclopropanes.

Infrared and Raman spectra of cyclobutane and cyclobutane-d8

Spectrochimica Acta Part A: Molecular Spectroscopy, 1972
Abstract New i.r. and Raman measurements are reported for cyclo butane and cyclo butane- d 8 . They include i.r. spectra on the gas at room temperature and on the solid at about 100°K. Raman spectra have been measured for the gas and liquid at room temperature and for the solid at 113°K. These data allow the assignments (for D 2d ) to be put on

Cyclobutane analogs of GABA

Neurochemical Research, 1980
Both cis- and trans-3-aminocyclobutane-1-carboxylic acid have been synthesized as conformationally restricted analogs of GABA. The cis isomer displayed weak to moderate GABA-like activity with respect to (1) inhibition of GABA uptake in rat brain minislices, (2) inhibition of sodium-independent binding of GABA to rat brain membranes, (3) activity as a ...
