The reaction of N-chloroacetyl derivatives 6-10 with morpholine yielded N-morpholin-1-yl acetyl derivatives 11-15 , which were subjected to Thorpe-Zieler cyclization with sodium tert -butoxide to produce the corresponding condensed pyridin-2(1H)-one derivatives 16-20 . Treatment of compounds 1 , 6-10 with either malononitrile or p -chlorobenzylidinemalononitrile in presence of triethylamine, afforded
N-氯乙酰基衍生物 6-10 与吗啉反应生成 N-morpholin-1-yl 乙酰基衍生物 11-15 ,将其与叔丁醇钠进行 Thorpe-Zieler 环化反应生成相应的缩合吡啶-2(1H) -一衍生物16-20。在三乙胺存在下用丙二腈或对氯苄基丙二腈处理化合物1、6-10,分别得到相应的嘧啶21-25、27和吡啶衍生物26。此外,用异硫氰基乙酸乙酯处理化合物1a,得到相应的哌嗪衍生物28。
