Thiazoles in glycosylation reactions: Novel synthesis of thiazole thioglycosides

Heteroatom Chemistry, 2017
AbstractThis research reports a novel method for synthesizing new thiazole thioglycosides. This series of thiazole thioglycosides were designed by the reaction of potassium cyanocarbonimidodithioate 2 with benzoyl acetonitrile 3a and ethyl bromoacetate 3b in the presence of ethanol‐KOH to give the corresponding potassium 4‐amino‐5‐substituted‐thiazole ...

MANGO‐“Fruitcage”: A Conditional Photocage Utilizing a Fluorescence Light‐Up Aptamer

Advanced Optical Materials, EarlyView.
Fruitcaging ‐ a proof of concept study of a conditional photocage (Thiazol‐Orange) activated upon binding to the fluorescence light up aptamer (Mango). The prolongation of the excited state lifetime explains the redirection of the reactive pathway toward photocleavage and provides a sensitive spectroscopic readout.
