摘要
Two novel aza-14-crown-4 ether derivatives bearing fused (Delta(3)-piperideino)[2,3-e] pyrimidine moieties as subunits were unexpectedly obtained as major products of a modified Petrenko-Kritschenko type cascade condensation of 1-benzyl-4-ethoxycarbonylpiperidin- 3-one with 1,5-bis(2-formylphenoxy)-3-oxapentane and ammonium acetate. X-ray structure study was performed to determine the structure of the compounds.
