Transition Metal-Mediated Cycloaddition Reactions
TL;DR: The phytochemical remains of the seven-membered ring formation are still under investigation, but it is clear that the polymethine content of the ring is lower than previously thought, suggesting that it is more likely to be a mixture of 22π and 32σ.
Journal ArticleDOI
Ring strain energies: substituted rings, norbornanes, norbornenes and norbornadienes
TL;DR: Ring strain energies (RSEs) were predicted using homodesmotic reactions at the B3LYP/6-31G* level of theory in this paper, and the effects of cis-1,2 disubstitution on RSEs have been evaluated and indicate stabilization for both small and medium sized rings.
Journal ArticleDOI
Cobalt-Catalyzed [2.pi. + 2.pi. + 2.pi.] (Homo-Diels-Alder) and [2.pi. + 2.pi. + 4.pi.] Cycloadditions of Bicyclo[2.2.1]hepta-2,5-dienes

Journal ArticleDOI
Ruthenium-catalyzed [2+2] cycloadditions of alkynyl sulfides and alkynyl sulfones.
Nicole Riddell,William Tam +1 more
TL;DR: Ruthenium-catalyzed [2+2] cycloadditions of bicyclic alkenes with alkynyl sulfide and sulfone moieties were investigated, giving the corresponding cyclobutene cycloadducts in good yields.
Journal ArticleDOI
Ruthenium-catalyzed [2 + 2] cycloadditions of ynamides.
TL;DR: The ynamide moiety was found to be compatible with the ruthenium-catalyzed cycloaddition conditions, giving the corresponding cyclobutene cycloadducts in moderate to good yields.
