1,3-Dipolar cycloaddition of nitrile oxides with C1-substituted 7-oxabenzonorbornadienes

Autor: R NagireddyJaipal, TamWilliam, CarlsonEmily

Publikováno v: Canadian Journal of Chemistry. 92:1053-1058

1,3-Dipolar cycloadditions of unsymmetrical C1-substituted 7-oxabenzonorbornadienes with acetonitrile oxide and benzonitrile oxide were investigated to probe the regio- and stereoselectivities of these reactions. All novel oxabicycle-fused isoxazolin

Regioselective palladium-catalyzed ring-opening reactions of C1-substituted oxabenzonorbornadienes

Autor: EdmundsMichael, RaheemMohammed Abdul, TamWilliam

Publikováno v: Canadian Journal of Chemistry. 92:888-895

The effect of ethyl and methoxycarbonyl substitution on the C1 position of oxabenzonorbornadienes undergoing palladium-catalyzed nucleophilic ring opening was investigated with a variety of aryl iodide nucleophiles. Electron-withdrawing groups in the

1,3-Dipolar cycloadditions of nitrile oxides with 7-oxa- and 7-azabenzonorbornadienes

Autor: TamWilliam, R NagireddyJaipal, CarlsonEmily

Publikováno v: Canadian Journal of Chemistry. 92:635-639

Dipolar cycloaddition reactions allow for the efficient construction of five-membered heterocycles, often with diverse medicinal applications. We examined the 1,3-dipolar cycloaddition of 7-oxabenzonorbornadienes and 7-azabenzonorbornadienes with ace

Ruthenium-catalyzed [2+2] cycloaddition reactions of a 2-oxa-3-azabicyclo[2.2.1]hept-5-ene with unsymmetrical alkynes

Autor: DurhamRobin, BlanchardNicolas, TamWilliam, MandelJérémie

Publikováno v: Canadian Journal of Chemistry. 89:1494-1505

Ruthenium-catalyzed [2+2] cycloaddition reactions of a 2-oxa-3-azabicyclo[2.2.1]hept-5-ene with unsymmetrical alkynes were investigated. Yields of up to 90% were obtained though regioselectivity was modest. Select cycloadducts could be separated and
