Mj. Alves et al., Novel aziridine esters by the addition of aromatic nitrogen heterocycles to a 2H-azirine-3-carboxylic ester, TETRAHEDR L, 41(25), 2000, pp. 4991-4995
Methyl 2-(2,6-dichlorophenyl)-2H-azirine-3-carboxoylate acts as an efficien
t alkylating agent for a variety of five-membered aromatic heterocycles. Th
e aziridines derived from heterocycles that bear an alpha-carbonyl substitu
ent react with TFA to give pyrroloimidazoles; 2,6-dichlorobenzaldehyde is a
lso produced. (C) 2000 Elsevier Science Ltd. All rights reserved.
