Synthesis and Characterization of Benzo-15-Crown-5 Ethers with Appended N(2)O Schiff Bases

New derivatives of benzo-15-crown-5 with flexible appended N(2)O unsymmetrical Schiff bases were prepared by a two step procedure which involves: (i) preparation of N(2)O Schiff bases by condensation of hydrazine with salicylaldehyde, 3-methoxysalicylaldehyde or 2-hydroxy-1-naphtaldehyde and (ii) re...

Sumario:New derivatives of benzo-15-crown-5 with flexible appended N(2)O unsymmetrical Schiff bases were prepared by a two step procedure which involves: (i) preparation of N(2)O Schiff bases by condensation of hydrazine with salicylaldehyde, 3-methoxysalicylaldehyde or 2-hydroxy-1-naphtaldehyde and (ii) reaction of the resulting NH(2) functionalized compounds with 4’-formyl-benzo-15-crown-5.
