A New Approach to Pyrrolophenanthridone Alkaloids via Intramolecular Radical Cyclization
TL;DR: In this article, a new approach to the synthesis of pyrrolophenanthridone class of alkaloids is described based on intramolecular radical cyclization of easily accessible 1-aroyl-7-bromoindoles with Bu3SnH and AIBN.
Journal ArticleDOI
Cycloaddition vs. Michael Addition in the Metal Halide/Amine-Induced Reactions of α-(Alkylideneamino) Esters with Electron-Deficient Olefins
TL;DR: In this paper, the lithiated intermediate derived from methyl 2-(benzylideneamino)propanoate and lithium bromide/triethylamine undergoes cycloaddition and Michael addition with methyl acrylate.
Journal ArticleDOI
N-(Trimethylsilylmethyl)pyridinium trifluoromethanesulfonates as facile precursors for nonstabilized pyridinium methylides.
TL;DR: As facile precursors for nonstabilized pyridinium methylides N-(trimethylsilylmethyl)pyrinium triflates were synthesized as discussed by the authors.
Journal ArticleDOI
Generation of Sulfur-Functionalized Nitrile Oxide, (Phenylthio)acetonitrile Oxide, and Synthetic Applications
TL;DR: The first generation of a new sulfur-functionalized nitrile oxide 1,3-dipole, (phenylthio)acetonitrile oxide, was presented in this paper.
Journal ArticleDOI
Photo-induced DNA Cleavage by Water-soluble Cationic Fullerene Derivatives
TL;DR: Fullerene derivatives 1a–c cleaved double stranded DNA under photo-irradiation through the action of singlet oxygen generated by the reaction of the photo-excited fullerenes with oxygen.
