Generalized iodolactonization conditions have been developed for the formation of both cis- and trans-γ-lactones from 3-pentenoic acid derivatives containing various protected alcohol moieties. Kinetic control of the reaction using iodine and base at 0 °C for 6 h provided the cis-lactone with good selectivity (75:25), and thermodynamic control at room temperature for 24 h provided the trans-lactone
通用碘内酯化条件已被开发用于从含有各种受保护醇部分的 3-戊烯酸衍生物形成顺式和反式 γ-内酯。使用碘和碱在 0°C 下对反应进行动力学控制 6 小时为顺式内酯提供了良好的选择性 (75:25),在室温下进行热力学控制 24 小时为反式内酯提供了出色的选择性 (98: 2)。
