, p. 143 - 146 (2014/04/17)
A mild and efficient synthesis of novel benzochromeno[2,3-d ]pyrimidine derivatives is described. A number of 8,10-dichloro- 7-aryl-7H-benzo[7,8] chromeno[2,3-d ]pyrimidines and 9,11-dichloro-12-aryl-12H-benzo[5,6]chromeno[2, 3-d ]pyrimidines were synthes
Synthesis of a novel piperidine-functionalized poly(ethylene glycol) bridged dicationic ionic liquid and its application in one-pot synthesis of substituted 2-amino-2-chromenes and 3,4-dihydropyrano[3,2-c]chromenes in aqueous media

, p. 1871 - 1876 (2014/01/06)
A novel piperidine-functionalized poly(ethylene glycol) bridged dicationic ionic liquid was prepared and identified. It was used as a recyclable catalyst for the synthesis of substituted 2-amino-2-chromenes and 3,4-dihydropyrano[3,2- c]chromenes with exce
