本文报道了用K2CO3作碱的固液相催化条件下, 醛亚胺与某些偶极试剂的1,3-偶极加成反应, 这些反应在质子性醇溶剂与K2CO3组成的两相体系中进行更为方便, 可用于吡咯烷及 唑烷衍生物的合成.

关键词: 吡咯烷 P, 碳酸钾, 相转移催化, 加成反应, 亚胺, 恶唑烷 P

The 1,3-dipolar cycloaddn. reactions of aldimines with some dipolarophiles under the solid-liq. phase transfer catalytic conditions using K2CO3 as a base is reported. The reactions are performed more conveniently in two phase systems consisting of alcohol solvents and K2CO3, and may be adapted for the synthesis of pyrrolidine and oxazolidine derivatives E.g., pyrrolidine I was prepared in 82% yield by treating PhCH:NCHMeCO2Me with 4-MeOC6H4CH:CHCOPh and K2CO3 in MeOH.

Key words: PYRROLIDINE P, POTASSIUM CARBONATE, PHASE TRANSFER CATALYSIS, ADDITION REACTION, IMINE
