Graphical Abstract
  • during the bioconjugate synthesis. The synthesis is carried out from a relatively non-expensive and commercially available H-Cys(trt)-(2-Cltrt) resin. The mode of linking the fluorophore to the growing peptide chain using a lysine derivative such as Fmoc-Lys(Tfa)-OH containing differentially protected

Graphical Abstract
  • shown in Scheme 4b and consists of acetone, hydrazine and OH−(H2O)7. The model is iso-electronic with the neutral one in Scheme 4a. Figure 3 exhibits geometric changes of the OH−-containing W-K reaction. The process of precursor (IMe) → CT complex (IIMe) → TS1 (IIIMe) → Me2C(OH)–NH–NH2 (IVMe) is similar
  • obtained, it was found to be unlikely because of the very large activation energy at the N2 extrusion step TS5, (xi). Second, elementary steps of OHcontaining two reactions were traced, where ketones are acetone and acetophenone. These results are summarized in Scheme 7. From the ketone to the hydrazone
