2,2-(1,3-丙烷二基二氧基)双苯甲醛 | 2-[3-(2-formylphenoxy)propoxy]benzaldehyde | 17954-12-0 | C17H16O4 | 284.312 |
The synthesis of new ‘reinforced’ O2N2- and O3N2-donor single macrocycles together with isomeric three-ring products is described. The new derivatives, which respectively incorporate intra- and inter-ring bridges between nitrogen donor atoms, were obtained on reaction of the parent membered macrocycles with 1,3-dibromopropane (or, in the case of the monomeric ‘reinforced’ rings, also 1,2-dibromoethane).
The syntheses of N-benzylated macrocyclic ligands incorporating O2N2-, O3N2- and O2N3-donor sets, and ring sizes from 15- to 18-membered, is described. The new derivatives were obtained by benzylation of the previously reported parent macrocycles with benzyl bromide in acetonitrile containing suspended sodium carbonate or bicarbonate. The X-ray structure determination of a tribenzylated product containing a 17-membered, O2N3-donor macrocyclic ring is described.
