Primary amines are diprotected as their 2,5-bis[(triisopropylsilyl)oxy]pyrrole derivatives (BIPSOP). This protecting group is stable to strong bases such as organolithiums and alkoxides at 0 °C and to temperatures up to about 150 °C. Removal may be accomplished by a mild two step sequence.
伯胺以其2,5-双[(三异丙基甲硅烷基)氧基]吡咯衍生物(BIPSOP)进行双保护。该保护基团在0°C以及高达约150°C的温度下对强碱(如有机锂和醇盐)稳定。去除可以通过温和的两个步骤完成。
