Alkyl–Alkyl Suzuki Cross‐Coupling of Unactivated Secondary Alkyl Chlorides [PDF]

open access: yesAngewandte Chemie, 2010
The first method for achieving alkyl–alkyl Suzuki reactions of unactivated secondary alkyl chlorides has been developed. Carbon–carbon bond formation occurs under mild conditions (at room temperature) with the aid of commercially available catalyst components.

DNA polymerase α (swi7) and the flap endonuclease fen1 (rad2) act together in the s-phase alkylation damage response in S. pombe [PDF]

open access: yes, 2012
Polymerase α is an essential enzyme mainly mediating Okazaki fragment synthesis during lagging strand replication. A specific point mutation in Schizosaccharomyces pombe polymerase α named swi7-1, abolishes imprinting required for mating-type switching ...

New catalytic strategies for DNA and RNA alkylation using rhodium (II) and copper (I) carbenes - a versatile tool for applications in chemical biology [PDF]

open access: yes, 2015
A variety of nucleic acid substrates were catalytically alkylated with rhodium(II) and copper(I)-carbenoids generated from diazocarbonyl compounds. The alkylation took place via an N-H insertion reaction selectively targeting the nucleobases in single ...

Catalytic Asymmetric Reductive Alkylation of Enamines to Chiral Aliphatic Amines [PDF]

open access: yes, 2020
Herein, we report a mild and general nickel-catalysed asymmetric reductive alkylation to effectively convert enamines—a class of important yet underexploited feedstock chemicals—into drug-like α-branched chiral amines and derivatives.

Catalytic Photochemical Enantioselective α-Alkylation with Pyridinium Salts [PDF]

open access: yes, 2022
We have developed a chiral amine catalyzed enantioselective α-alkylation of aldehydes with amino acid derived pyridinium salts as alkylating reagents. The reaction proceeds in the presence of visible light (390 nm) and in the absence of a photocatalyst ...

Progress of decreasing toxic polycyclic aromatic hydrocarbons content in coal-tar pitch by alkylation method

open access: yesMeitan kexue jishu, 2023
Coal-tar pitch (CTP) is a substance produced by ambient and/or vacuum distillation of high-temperature coal tar, although CTP has a large yield in China, however its wide application is limited due to its high toxicity.
