5-(1Z-carboxymethylene)-2-chloro-4,4-dimethoxycyclopent-2-en-1-ones have been prepared from the corresponding 3-N-substituted 5-allenyl-2,5-dichloro-4,4-dimethoxycyclopent-2-en-1-ones using selective oxidative cleavage of their allene bond by the RuCl3−NaIO4 system.
摘要 3-N-取代的 5-(1Z-carboxymethylene)-2-chloro-4,4-dimethoxycyclopent-2-en-1-ones 由相应的 3-N-取代 5-allenyl-2,5-dichloro -4,4-二甲氧基环戊-2-en-1-ones 使用 RuCl3-NaIO4 系统选择性氧化裂解
丙二烯键。
