摘要 在微波辅助下,Baylis-Hillman加成物与4-氨基-6-氯嘧啶或2-氨基-噻唑反应,快速合成了两类嘧啶酮衍生物——3-取代-7-氯-4H-嘧啶[1,2-b]哒嗪-4-酮和6-取代-5H-噻唑[3,2-a]嘧啶-5-酮,收率81%~98%,其结构经1H NMR,13C NMR,IR和MS确证。 Two types of pyrimidone,3-substituted-7-chloro-4H-pyrimidopyridazin-4-ones and 6-substituted-5H-thiazolopyrimidin-5-ones,were fastly synthesized from Baylis-Hillman adduct with 4-amine-6-chloropyrimide or 2-aminethiazole under microwave irritation in yields of 81%~98%.The structures were confirmed by 1H NMR,13C NMR,IR and MS.
