[reaction: see text]. We have previously described a diastereofacially selective 1,3-dipolar cycloaddition reaction of isomünchnones with vinyl ethers. While adapting this methodology for solid phase synthesis, we discovered a chemoselective and self-promoted linker aminolysis that provides liberated product in high purity, at a significantly enhanced rate. Herein we describe the implementation of a chiral
[反应:请参见文字]。先前我们已经描述了异麦草酮与
乙烯基醚的非对面选择性1,3-偶极环加成反应。在将这种方法用于固相合成的过程中,我们发现了一种
化学选择性和自我促进的接头
氨解反应,可以以显着提高的速率提供高纯度的游离产物。在本文中,我们描述了手性助剂作为固相连接剂的实现,其独特的
氨解作用的详细研究以及这种裂解在
化学多样性形式内的效用。
