Expanded genetic code approaches are a powerful means to add new and useful chemistry to proteins at defined residues positions. One such use is the introduction of non-biological reactive chemical handles for site-specific biocompatible orthogonal c

A photochemically chemically active noncanonical amino acid para-azido-L-phenylalanine widely used in biology was found to be metabolized by Saccharomyces cerevisiae. Contrary to multiple reports, the azide moiety is not reduced to the corresponding

The reactivity of two metallated nitrenium ions toward various substrates was examined in the gas phase. The nitrenium ions were generated by a reaction of benzoyl azide with laser-ablated Mg + or Cu + in a Fourier transform ion cyclotron resonance m

Carbomethoxyfluorocarbene was studied in solution by laser flash photolysis with UV-vis and infrared detection. In contrast to expectations, carbomethoxyfluorocarbene is more reactive than carbomethoxychlorocarbene. [structure: see text]

10-exo-Fluoro-10‘-endo-chlorotricylco[4.3.1.01,6]decadiene-2,4 (1) was synthesized. Continuous photolysis of 1 (300 nm) generates chlorofluorocarbene 2, which can be intercepted with tetramethylethylene (TME) to form the expected cyclopropane 3. La

Photolysis (254 nm) of methyl 8-chloro-3a,7a-methanoindan-8-carboxylate (5) in argon at 14 K produces carbomethoxychlorocarbene (6) as a persistent species. The IR and UV-vis spectra of the carbene were recorded and analyzed with the aid of density f

A new non-nitrogenous precursor of dimethylcarbene has been synthesized. Photolysis of 10,10′-dimethyltricyclo[4.3.1.0 1,6 ]deca-2,4-diene in solution with 254 nm light produces dimethylcarbene. Previously unknown intermolecular reactions of dimeth
