A commercially available ruthenium complex (first generation Grubbs’ carbene) was used for the catalytic deprotection of allylic amines (secondary as well as tertiary), by using for the first time reagents different from palladium catalysts. Interestingly, the catalytic system directs the reaction toward the selective deprotection of allylamines in the presence of allylic ethers.
使用了市售的
钌络合物(第一代格鲁布斯卡宾)首次通过不同于
钯催化剂的试剂,用于
烯丙胺(次级及三级)的选择性脱保护反应。值得注意的是,该催化体系在存在
烯丙醚的情况下,指导反应向
烯丙胺的选择性脱保护方向进行。
