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, 1972Abstract 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

Synthesis of Cyclobutane Nucleosides
Nucleosides, Nucleotides & Nucleic Acids, 20112-(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.

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 ...

On the barriers to planarity and the isotope effect in cyclobutane and cyclobutane-d8
Journal of Molecular Spectroscopy, 1975Abstract The infrared and Raman data on the ring-puckering vibration in cyclobutane and cyclobutane-d8 have been reexamined including the coordinate dependence of the reduced mass in the Hamiltonian. This was done for the purpose of estimating the importance of these small terms in the determination of barrier heights for four-membered rings and also

Cycloreversion of cyclobutanes
Theoretica Chimica Acta, 1980Semiempirical MO calculations with the method SINDO1 were performed to study the potential energy surface of cyclobutane and several substituted cyclobutanes with substituents F, OCH3 and CN. The reaction pathway with the lowest activation energy leading to two ethylenic fragments is nonconcerted.

Abstract The literature concerning the structures of compounds containing saturated, 4-carbon rings is reviewed critically, and the variety of conformations (dihedral angles of 0° to 30° ± 6°) of the cyclobutane ring are tabulated and discussed.
