Thiol-linked alkylation of RNA to assess expression dynamics

open access: yesNature Methods, 2017
Gene expression profiling by high-throughput sequencing reveals qualitative and quantitative changes in RNA species at steady state but obscures the intracellular dynamics of RNA transcription, processing and decay.

Direct C2–H alkylation of indoles driven by the photochemical activity of halogen-bonded complexes

open access: yesBeilstein Journal of Organic Chemistry, 2023
A light-driven metal-free protocol for the synthesis of sulfone-containing indoles under mild conditions is reported. Specifically, the process is driven by the photochemical activity of halogen-bonded complexes formed upon complexation of a sacrificial ...

Lead-Halide Perovskites for Photocatalytic α-Alkylation of Aldehydes.

open access: yesJournal of the American Chemical Society, 2019
Cost-effective and efficient photocatalysis are highly desirable in chemical synthesis. Here we demonstrate that readily prepared suspensions of APbBr3 (A = Cs or methylammonium (MA)) type perovskite colloids (ca.

Photoelectrochemical C-H Alkylation of Heteroarenes with Organotrifluoroborates.

open access: yesAngewandte Chemie, 2019
A photoelectrochemical method for the C-H alkylation of heteroarenes with organotrifluoroborates has been developed. The merger of electrocatalysis and photoredox catalysis provides a chemical oxidant-free approach for the generation and ...
