Total syntheses of oxygenated brazanquinones via regioselective homologous anionic Fries rearrangement of benzylic O-carbamates
Using new variations of anionic aromatic chemistry, the total synthesis of oxygenated brazanquinones (1a-1c), derived from beta-brasan, a natural product isolated from Caesalpina echinata, via carbamates 2a-2c is described.
متن کاملRegioselective nucleophilic addition of methoxybenzene derivatives to the beta-carbon of p-benzoquinone mono O,S-acetal.
Regioselective nucleophilic addition of electron rich aromatics to the beta-position of acetal carbon of p-benzoquinone mono O,S-acetal was achieved by modifying the acetal moiety.
متن کاملRegioselective sulfamoylation at low temperature enables concise syntheses of putative small molecule inhibitors of sulfatases.
Regioselective sulfamoylation of primary hydroxyl groups enabled a 5-step synthesis (overall yield 17%) of the first reported small molecule inhibitor of sulfatase-1 and 2, ((2S,3R,4R,5S,6R)-4,5-dihydroxy-2-methoxy-6-((sulfamoyloxy)methyl)tetrahydro-2H-pyran-3-yl)sulfamic acid, which obviated the use of hydroxyl protecting groups and is a marked improvement on the reported 9-step synthesis (ove...
متن کاملCarbohydrates to Pyrano-Furanoids: New and Regioselective Palladium-Catalyzed Syntheses of Tetrasubstituted Furanoids from Carbohydrate Scaffolds
Furanoids are important targets either as a key entity itself or as a substructure that represents the framework of many biologically significant natural products [1]. Therefore, their access has attracted the interest of many groups [2], Voelter et al. have described elegant strategies for the syntheses of furanoids using two different approaches, either mono or dianions derived from 1,3-dicar...
متن کاملRegioselective syntheses of fully-substituted 1,2,3-triazoles: the CuAAC/C-H bond functionalization nexus.
Regioselective syntheses of 1,4,5-trisubstituted 1,2,3-triazoles were accomplished by three different strategies, relying on (i) the interception of stoichiometrically formed 5-cuprated-1,2,3-triazoles, (ii) the use of stoichiometrically functionalized alkynes or (iii) catalytic C-H bond functionalizations. This perspective article summarizes progress in this research area until June 2010.
