Regioselectivity in cross-coupling reactions of 2,6,8-trichloro-9- (tetrahydropyran-2-yl)purine: Synthesis of 2,6,8-trisubstituted purine bases
The regioselectivity of cross-coupling reactions (Pd-catalyzed Suzuki-Miyaura reactions with phenylboronic acid and Fe-catalyzed reactions with methylmagnesium chloride) of 2,6,8-trichloro-9-(tetrahydropyran-2-yl)purine with varying amounts of the organom
