Strain engineering of single-site Cu on SWCNTs for highly efficient diene cyclopropanation

Nature Communications
Cyclopropane-based aerospace fuels exhibit the excellent volumetric calorific value, leading to broad application prospects in aircrafts. However, due to the highly rigid structure of the cyclopropane (compared to cyclobutane or cyclopentane, etc.) and ...

Determination of Cyclopropane Fatty Acids in Food of Animal Origin by 1H NMR

Journal of Analytical Methods in Chemistry, 2018
Cyclopropane fatty acids (CPFAs) are unusual fatty acids of microbial origin, recently detected in milk and dairy products. CPFAs have been demonstrated to be interesting molecular markers for authentication of dairy products obtained without ensiled ...

Asymmetric and Regiospecific Synthesis of Isotopically Labelled Cyclopropane Fatty Acid (9R,10S)-Dihydrosterculic Acid: Overcoming Spontaneous Protonation During Lithium-Sulfoxide Exchange­

SynOpen, 2018
The total synthesis of isotopically labelled (9R,10S)-dihydro­sterculic acid, a usual cyclopropane fatty acid with biologically relevant toxicity upon desaturation in vivo, is reported. A diastereoselective Corey­–Chaykovsky reaction was employed to form

Raman Spectrum of Cyclopropane

, 1936
The Raman spectrum of cyclopropane is of great interest in view of the fact that it is the simplest of the cyclic hydrocarbons, and also from the point of view of the structure of the cyclopropane molecule.

Cyclopropane-Containing Polyamine Analogues Are Efficient Growth Inhibitors of a Human Prostate Tumor Xenograft in Nude Mice

, 2016
Polyamine analogues 7, 10, 18, 27, and 32 containing cyclopropane rings were obtained by chemical synthesis. Their antineoplastic activities were assessed against the cultured human prostate tumor cell lines DU-145, DuPro, and PC-3.
