Synthesis of Tris- and Tetrakis(tropocoronand)s Having Short Linker Chains
摘要:
The syntheses of tris- and tetrakis(tropocoronand)s, a kind of macrocycles derived three or four aminotropone imine moieties bridged by three or four short methylene linker chains are described. These tropocoronands were prepared by the reaction of bis(2-methoxytropone imine)salts with alpha,omega-alkanediamine using a template or with tropopodand derived from benzo[b]cyclohepta[e][1,4]oxazine with N-acetyl-1,2-ethanediamine by an intermolecular heterocycle exchange reaction.
