The benign synthesis of bioactive heterocycles using photochemistry and hydrogen peroxide with hydrohalic acids
Gurry, Michael (2016-07-08)Chapter 1 provides a pertinent review of recent photochemical homolytic aromatic substitution (HAS) literature. Photochemical methods for HAS include UV-light and visible light photoredox catalysis. Recently invented methods ... -
Greener synthesis using hydrogen peroxide in ethyl acetate of alicyclic ring-fused benzimidazoles and anti-tumour benzimidazolequinones
Sweeney, Martin; Gurry, Michael; Keane, Lee-Ann J.; Aldabbagh, Fawaz (Elsevier BV, 2017-09-01) -
A new era for homolytic aromatic substitution: replacing Bu3SnH with efficient light-induced chain reactions
Gurry, Michael; Aldabbagh, Fawaz (Royal Society of Chemistry, 2016-04-01)Herein is a pertinent review of recent photochemical homolytic aromatic substitution (HAS) literature. Issues with using the reductant Bu3SnH in an oxidative process where the net loss of a hydrogen atom occurs is discussed. ... -
One-pot hydrogen peroxide and hydrohalic acid induced ring closure and selective aromatic halogenation to give new ring-fused benzimidazoles
Gurry, Michael; Sweeney, Martin; McArdle, Patrick; Aldabbagh, Fawaz (American Chemical Society, 2015-05-19)A new series of selectively dichlorinated and dibrominated five- to eight-membered-ring [1,2-a]-fused benzimidazoles and [1,4]oxazino[4,3-a]benzimidazoles are synthesized in mostly high yields of >80% using the reaction ... -
One-pot hydrogen peroxide and hydrohalic acid induced ring closure and selective aromatic halogenation to give new ring-fused benzimidazoles
Gurry, Michael; Sweeney, Martin; McArdle, Patrick; Aldabbagh, Fawaz (American Chemical Society (ACS), 2015-06-05)A new series of selectively dichlorinated and dibrominated five- to eight-membered-ring [1,2-a]-fused benzimidazoles and [1,4]oxazino[4,3-a]benzimidazoles are synthesized in mostly high yields of >80% using the ... -
Photochemical aryl radical cyclizations to give (e)-3-ylideneoxindoles
Gurry, Michael; Allart-Simon, Ingrid; McArdle, Patrick; Gérard, Stéphane; Sapi, Janos; Aldabbagh, Fawaz (MDPI AG, 2014-09-30)(E)-3-Ylideneoxindoles are prepared in methanol in reasonable to good yields, as adducts of photochemical 5-exo-trig of aryl radicals, in contrast to previously reported analogous radical cyclizations initiated by ... -
Synthesis of a spirocyclic oxetane-fused benzimidazole
Gurry, Michael; McArdle, Patrick; Aldabbagh, Fawaz (MDPI AG, 2015-07-30)A new synthesis of 2-oxa-7-azaspiro[3.5]nonane is described. Spirocyclic oxetanes, including 2-oxa-6-azaspiro[3.3]heptane were converted into o-cycloalkylaminoacetanilides for oxidative cyclizations using Oxone((R)) in ...
