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 ...

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 ...

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. ...
End-group differentiating ozonolysis of norbornene systems to access to highly substituted cyclopentane rings
(Wiley, 2013-05)
The end-group-differentiating ozonolysis concept is discussed, with an emphasis on norbornene systems. Different remote functional groups in endo positions in norbornene derivatives are able to direct the primary ozonide ...
