Amidines react in the presence of NaHCO3 with β-chlorovinyl ketones, prepared regioselectively by the reaction of 2-acetylcyclo- pentanone-type diketones with PPh3-CCl4 in 73–78% yield, to afford 2-alkyl (aryl)-pyrimidines annelated with cyclopentane derivatives in 79–87% yields.
脒在 NaHCO3 存在下与 β-氯乙烯基酮反应,β-氯乙烯基酮是通过 2-乙酰环戊酮型二酮与 PPh3-CCl4 以 73-78% 的产率反应制备的,得到 2-烷基(芳基)-嘧啶环戊烷衍生物的产率为 79-87%。
