Synergistic Catalysis: Asymmetric Synthesis of Cyclopentanes Bearing Four Stereogenic Centers

open access: yesSynthesis, 2017
We present a formal [3+2] cycloaddition based on synergistic catalysis. Vinylcyclopropanes derived from cyanoesters react with enals by dual activation using palladium(0) and secondary amines to form the corresponding cyclopentanes in good yields and ...

Muscarinic thioligands with cyclopentane nucleus

Bioorganic & Medicinal Chemistry, 1996
Some thio- and the benzoyl-derivatives of deoxamuscarine were synthesized and tested as muscarinic agonists using radioligand binding assays and functional tests. In comparison with deoxamuscarine, used as reference compound, no dimension/distance modification is tolerated for correct lipophilic pocket recognition.

A study of the fragmentation of cyclopentane‐1,3‐diols and of cyclopentane‐1,2,4‐triols

Organic Mass Spectrometry, 1975
AbstractThe mass spectra of the two cyclopentane‐1,3‐diol and of the three cyclopentane‐1,2,4‐triol stereoisomers have been studied. Extensive deuterium labelling allows the detection of complex processes, especially for the elimination of water from the [M – H2OO]+· and [M]+· ions.

Decomposition of cyclopentane on Ni(755): peculiar decomposition behavior of cyclopentane

Surface Science Letters, 1993
Abstract Decomposition of cyclopentane on Ni(755) and −(111) has been investigated by temperature-programmed desorption (TPD). Adsorption of cyclopentane occurs on both surfaces by a precursor-mediated mechanism. On the (755) surface cyclopentane decomposes almost completely into adsorbed carbon and gaseous hydrogen while heating up from 123 to 573 K.
