Product Details of 37943-90-1. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: Diphenyl-2-pyridylphosphine, is researched, Molecular C17H14NP, CAS is 37943-90-1, about Installation of Minimal Tetrazines through Silver-Mediated Liebeskind-Srogl Coupling with Arylboronic Acids. Author is Lambert, William D.; Fang, Yinzhi; Mahapatra, Subham; Huang, Zhen; am Ende, Christopher W.; Fox, Joseph M..
Described is a general method for the installation of a minimal 6-methyltetrazin-3-yl group via the 1st example of a Ag-mediated Liebeskind-Srogl cross-coupling. The attachment of bioorthogonal tetrazines on complex mols. typically relies on linkers that can neg. impact the physiochem. properties of conjugates. Cross-coupling with arylboronic acids and a new reagent, 3-((p-biphenyl-4-ylmethyl)thio)-6-methyltetrazine (b-Tz), proceeds under mild, PdCl2(dppf)-catalyzed conditions to introduce minimal, linker-free tetrazine functionality. Safety considerations guided the authors’ design of b-Tz which can be prepared on decagram scale without handling hydrazine and without forming volatile, high-N tetrazine byproducts. Replacing conventional Cu(I) salts used in Liebeskind-Srogl cross-coupling with a Ag2O mediator resulted in higher yields across a broad library of aryl and heteroaryl boronic acids and provides improved access to a fluorogenic tetrazine-BODIPY conjugate. A covalent probe for MAGL incorporating 6-methyltetrazinyl functionality was synthesized in high yield and labeled endogenous MAGL in live cells. This new Ag-mediated cross-coupling method using b-Tz is anticipated to find addnl. applications for directly introducing the tetrazine subunit to complex substrates.
