Fluorogenic reactions in which non- or weakly fluorescent reagents produce highly fluorescent products can be exploited to detect a broad range of compounds including biomolecules and materials. We describe a modified dibenzocyclooctyne that under catalyst-free conditions undergoes fast strain-promoted cycloadditions

New Aromatic Terminal Alkynes

The terminal alkyne functionality has a wide range of applications including most recently the synthesis of spiropyran substituted 2,3-dicyanopyrazines and (±)-asteriscanolide, as well as conversion to enamines using resin-bound 2° amines.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
