Monocyclic as well as fused bicyclic systems with a nitrogen 10 atom at the bridgehead, including indolizidines and quinolizidines, can be prepared in four steps from N-Boc β-lactams. These easily prepared, highly robust, and flexible building blocks allow the incorporation of chirality and structural diversity, rendering the method feasible for diversity- as well as target-oriented synthesis.
N -Boc β-内酰胺可以通过四步制备单环和稠合双环系统,在桥头处有一个 10 原子的氮原子,包括吲哚里西啶和喹尼西啶。这些易于制备、高度稳健且灵活的构建模块允许结合手性和结构多样性,使该方法适用于多样性以及面向目标的合成。
