TCO (trans-cyclooctene) Derivatives: The Fastest Click Reaction Reagents
TCO (trans-cyclooctene) derivatives form covalent bonds with tetrazines in a strain-promoted, Inverse Electron-Demand Diels-Alder Reaction. Since this reaction can be used as a fast click reaction without the need for metal catalysts, TCO (trans-cyclooctene) derivatives are widely used for protein labeling and imaging.
Cobalt Complexes for Oxidant-Free Dehydrogenative Cross Coupling
Co(dmgH)2(DMAP)Cl [C3711] aromatizes cyclohexane rings through the dehydrogenative reaction using a photoredox catalyst, without the need of oxidants or hydrogen acceptors. It also be applicable to the dehydrogenative C-N and C-S bond formation reactions and dehydrogenation of nitrogen-containing heterocycles
Sulfonyl Azide Useful for Introduction of Azido and Diazo Groups
2,4,6-Triisopropylbenzenesulfonyl azide [T3434] can be used as an electrophilic azidation agent or a diazotization agent. When T3434 reacts with a suitable base on a substrate containing a carbonyl group, an azido or diazo group can be introduced at the α-position. Recently, decarboxylative azidation reactions using visible light redox catalysts have also been reported.
Introduction of Cyano Group with Homologation Using TosMIC
We are proud to present the synthesis of 2-cynoadamantane with homologation using TosMIC [T1046]. TosMIC is an easy-to-handle and almost odorless solid.Upcoming Events
