Efficient syntheses of 2,3-disubstituted natural quinazolinones via iridium catalysis.
Natural products sclerotigenin, pegamine, deoxyvasicinone, mackinazolinone, and rutaecarpine were synthesized. Core quinazolinone structures were constructed via Ir catalysis.
متن کاملIridium catalysed synthesis of piperazines from diols.
A green and atom-economical method has been developed for the synthesis of piperazines by cyclocondensation of diols and amines in aqueous media in the presence of a catalytic amount of [Cp*IrCl2]2.
متن کاملIridium-catalysed regioselective borylation of carboranes via direct B–H activation
Carboranes are carbon-boron molecular clusters, which can be viewed as three-dimensional analogues to benzene. They are finding many applications in medicine, materials and organometallic chemistry. On the other hand, their exceptional thermal and chemical stabilities, as well as 3D structures, make them very difficult to be functionalized, in particular the regioselective functionalization of ...
متن کاملEnantioselective synthesis of almorexant via iridium-catalysed intramolecular allylic amidation.
An enantioselective synthesis of almorexant, a potent antagonist of human orexin receptors, is presented. The chiral tetrahydroisoquinoline core structure was prepared via iridium-catalysed asymmetric intramolecular allylic amidation. Further key catalytic steps of the synthesis include an oxidative Heck reaction at room temperature and a hydrazine-mediated organocatalysed reduction.
متن کاملHighly enantioselective iridium-catalysed allylic aminations with anionic N-nucleophiles.
Iridium-catalysed allylic substitutions with anionic N-nucleophiles were achieved with regioselectivity of up to 49:1 and enantiomeric excess of up to 98%.
