Activated 1-alkenes such as ketene dithioacetals, vinyl sulfides, N-vinyl amides, and N-vinylcarbazole react with oxalyl chloride or ethoxalyl chloride in the presence of pyridine to give the 2-oxo-3-alkenoic acids or ethyl esters, respectively.
活化的1-烯烃,如酮烯硫代乙酸酯、乙烯硫化物、N-乙烯基酰胺和N-乙烯基咔唑,在吡啶存在下与氯化草酰或氯化乙氧草酰反应,分别生成2-氧代-3-烯酸或其乙酸酯。
