Interaction between the peroxide adduct of binuclear iron(III) complex with (HPTP) anion and the sugar moiety of nucleosides
We have in this study obtained the experimental evidence to suggest that the peroxide adduct of binuclear iron(III) complex with H(HPTP) directly reacts with the sugar moiety of the DNA chain, to cleave it; H(HPTP) denotes N,N,N′,N′-tetrakis(2-pyridylmeth
Heteroarylation of Ethers, Amides, and Alcohols with Light and O2
An efficient protocol for the Cα-H heteroarylation of ethers, amides, and alcohols using air and light under mild conditions is described. The reaction is applicable to a wide spectrum of functional groups. The generation of C-radicals via photoinduced aerobic oxidation of ethers, amides, and alcohols is the key feature of the process. Control experiments suggest a radical pathway for the reaction.
Cleavage of a carbon-carbon triple bond via gold-catalyzed cascade cyclization/oxidative cleavage reactions of (2)-enynols with molecular oxygen
A highly efficient carbon-carbon triple bond cleavage reaction of (Z)-enynols was developed, which offered a new route to highly substituted butenolides. The methodology is realized by a tandem reaction using a single gold(I) catalyst, which could catalyze different reactions of cyclization/oxidative cleavage in the same vessel. Copyright
