(Z)-Dimethyl α-(bromomethyl)fumarate, an efficient intermediate for the selective synthesis of dimethyl 3-alkyl itaconates and 2-alkyl 3-carbomethoxy-γ-lactams
摘要:
(Z)-Dimethyl alpha-(bromomethyl)fumarate 2 proved to be an efficient precursor of 3-substituted itaconic acid esters 3 via its reaction with magnesium dialkylcuprates. Some hindered esters 3 can be used for the diastereoselective synthesis of alpha-alkylated-beta-methoxycarbonyl-gamma-lactams 6. (C) 1999 Elsevier Science Ltd. All rights reserved.
