Tetrahedron, 1974
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.

A Cyclobutane possessing Hypotensive Activity
Nature, 1964A NUMBER of non-quaternary bases have been found to possess ganglionic blocking and hypotensive properties1–5. In investigating the pharmacological properties of a new series of cyclobutanes6, one of them, 3-dimethylamino-2,2,4,4-tetramethyl-cyclobutanol, was found to exhibit a lowering activity of the blood pressure of long duration.

Functionalized Cyclobutanes via Heck Cyclization
Organic Letters, 2007Heck-type 4-exo-trig cyclization of linear 2-enol triflate-1,5-hexadienes provides functionalized methylene cyclobutanes. Intramolecular palladium coordination can initiate beta-hydride elimination leading to 1,2-dimethylene cyclobutane derivatives, which are obtained with high selectivity if substrates having a geminal diphenyl group at Calpha are ...

Carbon‐13 NMR spectra of methylated cyclobutanes and ethyl cyclobutane‐carboxylates
Organic Magnetic Resonance, 1980AbstractThe 13C NMR spectra of cyclobutane and seven methylated homologs and of ethyl cyclobutanecarboxylate and five isomeric diethyl cyclobutanedicarboxylates are reported and substituent parameters for methyl groups in methylcyclobutanes are calculated. Of note is a sizeable and nearly configuration‐independent upfield shifting γ‐effect.
