The sesquiterpene lactones cover a diverse and pharmacologically important diversity space. In particular, the electrophilic α-exo-methylene-γ-butyrolactone moiety that is preponderant in this natural product family has been shown to readily engage in covalent inhibition via conjugate addition of cysteine residues in target proteins. However, the synthetic accessibility of sesquiterpenes or related
倍半萜内酯涵盖了多种多样且在药理学上很重要的多样性空间。特别地,已经显示出在该天然产物家族中占优势的亲电α-外-亚甲基-γ-丁内酯部分易于通过共轭添加靶蛋白中的半胱氨酸残基而参与共价抑制。然而,倍半萜烯或相关探针的合成可及性用于研究其作用方式仍然很费力。在本文中,我们提出了一种快速且可扩展的手性溴内酯途径,以作为倍半萜内酯合成中的前体。
