Investigation of the regioselectivity of alkylation of 3-nitropyridin-2(1H)-ones
Kislyi,Semenov
, p. 460 - 463 (2001)
Alkylation of 3-nitropyridin-2(1H)-ones in the presence of bases affords N-alkylated products and sometimes O-alkylated products. The yields and relative amounts of N- and O-alkylated products depend substantially on the size of the substituent at the C(6
