Hikawa, Hidemasa published the artcileA borrowing hydrogen methodology: palladium-catalyzed dehydrative N-benzylation of 2-aminopyridines in water, Name: (4-Butoxyphenyl)methanol, the main research area is benzyl aminopyridine green preparation KIE; aminopyridine benzyl alc dehydrative monobenzylation palladium catalyst base free.
A greener borrowing hydrogen methodol. using the π-benzylpalladium system, which offered an efficient and environmentally friendly preparation of N-benzyl aminopyridines I [R1 = H, 5-F, 3-Me, etc.; R2 = H, 3-Me, 4-t-BuO, etc.; R3 = H, Me] via dehydrative N-monobenzylation of 2-aminopyridines with benzylic alcs. in the absence of base was demonstrated. The crossover experiment using benzyl-α,α-d2 alc. and 3-methylbenzyl alc. afforded H/D scrambled products, suggesting that the dehydrative N-benzylation in the catalytic system involved a borrowing hydrogen pathway. KIE experiments showed that C-H bond cleavage at the benzylic position of benzyl alc. was involved in the rate-determining step (KIE = 2.9). This simple base-free protocol could be achieved under mild conditions in an atom-economic process, affording the desired products in moderate to excellent yields.
