Oxidative catalytic removal of hydrocarbons over Pt/Al2O3 catalysts
(Elsevier Science, 2000-12)
The reaction kinetics, structure sensitivity, and in situ activation of cyclopentane and methane combustions were studied on Pt/Al2O3 catalysts of different platinum and chlorine loadings. The catalyst activities were ...
Stereochemistry of cyclopentane derivatives from (2,3)J(CH) dependence on dihedral angle (theta H-C-C-X)
(JOHN WILEY & SONS LTD, 2008)
The (2,3)J(CH) dependence on dihedral angle (theta H-C-C-X) for cyclopentane derivatives was investigated. We observed that the combined use of experimentally obtained (2,3)J(CH) values and the theoretically determined ...

The absolute configuration of 1-(3 ',4 '-dihydroxycinnamoyl)cyclopentane-2,3-diol from the Amazonian tree Chimarrhis turbinata
(Amer Chemical Soc, 2006-07-28)
An antioxidant, 1-(3',4'-dihydroxycinnamoyl) cyclopentane-2,3-diol [ or ( E)-2,3-dihydroxycyclopentyl-3-(3',4'-dihydroxyphenyl) acrylate ( 1)], and two known trans- and cis-chlorogenic acid methyl esters were isolated from ...

Communiols E-H: New polyketide metabolites from the coprophilous fungus Podospora communis
(2005-03-01)
Communiols E-H (1-4), four new polyketide-derived natural products containing furanocyclopentane, furanocyclopentene, cyclopentene, or γ-lactone moieties, have been isolated from two geographically distinct isolates of the ...

Total synthesis of (3S, 5R, 3'S, 5'R)-capsorubin
(Sociedade Brasileira de Química, 2009)
The total synthesis of enantiomerically enriched (3S, 5R, 3'S, 5'R)-capsorubin (1) by aldol condensation of (1R, 4S)-1-(4-hydroxy-1,2,2-trimethyl-cyclopentyl) ethanone (2a) and crocetindial (3) is described. An alternative, ...
Cross metathesis of several methylenecyclopentane derivatives
(Elsevier, 2013-07)
The cross metathesis (CM) of several methylenecyclopentane derivatives using HoveydaeGrubbs second generation catalyst 4 (5e10 mol %) has been studied. Medium to good yields of tetrasubstituted alkenes have been obtained. ...
