[2+2]大环Schiff碱的非模板法合成

SYNTHESES OF[2+2]MACROCYCLIC SCHIFF BASES BY NON--TEMPLATE METHOD

由5—位取代的2—甲氧基—1.3—苯二甲醛与乙二胺、丙二胺在无水乙醇中缩合,非模板法合成了九个新的正[2+2]大环Schif碱。所以化合物均经IR,＇HNMR和元素分析确证。

Nine new [2+2] macrocyclic Schiff bases were synthesized via the reaction of 5-R-2-methoxyl-isophthaldehyde (R=CH_3, OCH_3, C1, Br, Ph)with 1,2- diaminoethane or 1,3-diaminopropane by non-template method. All compounds were verified by IR ~1HNMR and microanalyses.
