A new synthetic protocol for efficient and regiospecifc assembly of indolizines and pyrido[1,2-a]indoles by coupling of substituted methyl bromides and alkynes with corresponding pyrrole-2-carboxaldehyde and 1H-indole-2-carboxaldehyde has been developed. Additionally, a possible mechanism for the reaction is proposed.

Toward new biotechnology by genetic alphabet expansion, we developed an efficient site-specific labeling method for large RNA molecules. The combination of unnatural base pair transcription and post-transcriptional modification by click chemistry enables simple RNA labeling with a wide variety of...

Intermolecular interactions relevant for antiparallel beta-sheet formation between peptide strands are studied by Fourier transform infrared spectroscopy of the low temperature, vacuum-isolated model compound pyrrole-2-carboxaldehyde and its dimer in the N-H and C=O stretching range. Comparison to quantum chemical predictions...

Fluorescent labeling of nucleic acids is widely used in basic research and medical applications. We describe the efficient site-specific incorporation of a fluorescent base analog, 2-amino-6-(2-thienyl)purine (s), into RNA by transcription mediated by an unnatural base pair between s and...
