本論文報告了3-alkyl-1-isoindolinone有效率、簡明的新合成方法。經由phthalimide透過有機鋰的烷基化反應得到3-alkyl-3-hydroxy-2,3-dihydro-1-isoindolinones,將其在酸性環境下利用cyanoborohydrate進行脫水,同時進行還原反應製備出種種的3-alkyl-1-isoindolinones,並且得到高的產率。
A new, concise, and efficient method for the synthesis of 3-alkyl-1-isoindolinone was described. 3-Alkyl-3-hydroxy-2,3-dihydro- 1-isoindolinones, prepared from the reaction of phthalimide and alkyl lithium, were respectively treated with sodium cyanoborohydride in acidic medium to concomitantly undergo dehydration and reduction to lead to various 3-alkyl-1- isoindolinones in good yields.
