Nesterova, I. N.,Grinev, A. N.,Rubtsov, N. M.
, p. 55 - 57 (2007/10/02)
Ethyl esters of α-(3-chloro-1,4-naphthoquinon-3-yl)crotonic or cinnamic acids were obtained by the reaction of 2,3-dichloro-1,4-naphthoquinone with ethyl esters of N-substituted β-aminocrotonic or β-aminocinnamic acids.These esters were converted by alkal
