One-Step Synthesis of 2-Fluoroadenine Using Hydrogen Fluoride Pyridine in a Continuous Flow Operation
Contributor(s):: Salehi Marzijarani, Nastaran, Snead, David R., McMullen, Jonathan P., Lévesque, François, Weisel, Mark, Varsolona, Richard J., Lam, Yu-hong, Liu, Zhijian, Naber, John R.
We report the development of a one-pot synthesis of 2-fluoroadenine from an inexpensive 2,6-diaminopurine starting material using diazonium chemistry in a continuous fashion. Given the sensitivity of this transformation to temperature, we conducted critical experiments to study the exothermicity...
