Two types of fused pyrimidones, 3-substituted-7-chloro-4H -pyrimido[1,2-b]pyridazin-4-ones and 6-substituted-5H-thiazolo-[3,2-a]pyrimidin-5-ones were easily prepared from Baylis-Hillman adduct acetates under microwave irritation in high yields.
两种稠合嘧啶酮,3-取代-7-氯-4H-嘧啶并[1,2-b]哒嗪-4-酮和6-取代-5H-噻唑并-[3,2-a]嘧啶-5-酮在微波刺激下,由 Baylis-Hillman 加合物醋酸盐很容易以高产率制备。
