Web2 days ago · For this purpose, we employ the tetrazine – thiol exchange (TeTEx) reaction as a fully traceless click reaction with second order rate constants k2 up to 25 M-1 s-1 within aqueous environments. Employing TeTEx as a reversible click reaction for the chemoselective modification of biomolecules is made possible by the use of asymmetric … WebOct 18, 2024 · Having identified optimal reaction conditions, we initially examined chemoselective couplings of multihalogenated aromatics with furanosyl acetate 4 (Scheme 1). Surprisingly, a range of aryl iodides bearing bromo and chloro groups in the para - and meta -positions reacted in good-to-excellent yields to deliver the desired products ( 12 , … how far is gulfport ms to new orleans la
