Methods for fluorescent probing at a defined position of RNA provide powerful tools for analyzing the local structural conformation of functional RNA molecules by tracking fluorescence changes. In this article, we describe the site-specific fluorescent probing of RNA by transcription...

An unnatural base pair between 7-(2-thienyl)-imidazo[4,5-b]pyridine (Ds) and pyrrole-2-carbaldehyde (Pa) could expand the genetic alphabet and allow the incorporation of non-standard amino acids into proteins at defined positions. For this purpose, we synthesized tRNAs bearing Pa at the anticodon and...

A regiocontrolled synthesis of 3,4-disubstituted pyrrole-2-carboxaldehydes was completed in two steps from acyclic starting materials. A Barton-Zard pyrrole synthesis between N-methoxy-N-methyl-2-isocyanoacetamide and alpha-nitroalkenes or beta-nitroacetates provided N-methoxy-N-methyl pyrrole-2-carboxamides (pyrrole Weinreb amides), which were converted into the corresponding pyrrole-2-carboxaldehydes by treatment...

Monomeric pyrrole-2-carbaldehyde (P2C) was isolated in low-temperature argon and xenon matrices, and its UV-induced photochemistry was studied. The structures of the reagent as well as the reaction photoproducts were characterized by FTIR spectroscopy. Interpretation of the experimental results was assisted...

A series of 3-methylidene-1H-indol-2(3H)-ones substituted with a 5- or 6-pentafluorosulfanyl group has been synthesized by a Knoevenagel condensation reaction of SF
