Stereoselective synthesis of a ketohexofuranose from an aldohexopyranose by a [6+1−1] strategy
TL;DR: This methodology allows specific deuteration at C-1 of a protected D-fructofuranose derivative and could serve as [6+1-1] formulation for hexose series inter-conversion, that is, aldohexopyranose to ketohex ofuranose.
Journal ArticleDOI
A new route to the synthesis of 3-methylenecoumarins-via Lewis acid catalyzed rearrangement of methyl α-aryloxymethylacrylates
TL;DR: Methylα-aryloxymethylacrylates as discussed by the authors have been found to rearrange to furnish the methylenecoumarins when refluxed in methylene chloride in the presence of anhydrous AlCl 3.
Journal ArticleDOI
Synthesis, characterization, in vitro, and in silico studies of 4-(2′-hydroxybenzoyl) and 4-(2′-hydroxynaphthoyl)-thiabenzene-1-methyl-1-oxides

TL;DR: In this paper, a variety of 4-(2′-hydroxybenzoyl) and 4-hydroxynaphthoyl thiabenzene-1-methyl-1oxides have been prepared by the reaction of dimethylsulfoxoniummethylmethylide with 3-formyl-chromones and screened screened...
Journal ArticleDOI
Radical cyclisation : synthesis of 4H-furo(3,2-c)-1-benzopyrans
TL;DR: In this article, 3,4-dihydro-3-bromo-4-(prop-2-ynyloxy)-2H-1-benzopyrans (3) undergo radical cyclisation when treated with nBu 3 SnH and AIBN.
Journal ArticleDOI
Intramolecular competitive addition of vinyl radicals to keto and alkenyl groups in Wieland–Miescher ketones—synthesis of carbocycles and propellanes
TL;DR: Wieland-Miescher ketone analogues are prepared by monoalkylation of cyclohexane-1,3-dione with bromomethylcycloalkenyl bromides followed by annulation with methyl vinyl ketone; they undergo 5-exo-trig competitive intramolecular radical addition to the keto and enone olefins to give angularly rused carbocycles and propellanes, respectively as discussed by the authors.
