Ideal for scaffold diversity synthesis: The first organocatalytic direct vinylogous Michael addition of N‐Boc α,β‐unsaturated γ‐butyrolactam to α,β‐unsaturated aldehydes has been developed. The products with multiple orthogonal sets of functionalities were transformed into diverse enantioenriched natural‐product‐like or drug‐like molecules with fused bi‐, tri‐, or polycyclic scaffolds (see scheme)
支架多样性合成的理想选择:首次开发了N - Bocα ,β-不饱和γ-丁内酰胺向α,β-不饱和醛的有机催化直接乙烯基迈克尔加成反应。具有多个正交功能集的产品被转化为具有融合的双环,三环或多环支架的丰富的对映体富集的天然产物样或药物样分子(参见方案),这可能具有生物学相关的研究潜力。
