Allylic sulfones are important building blocks in organic synthesis and pharmaceutical chemistry. Herein, we disclose a chemodivergent protocol for Pd-catalyzed and ligand-controlled coupling of allenes with sulfinic acids, providing straightforward and atom-economical access to branched allylic sulfones and linear allylic sulfones bearing a conjugated (Z,E)-1,3-diene scaffold in good yields with high
烯丙基砜是有机合成和药物化学中的重要组成部分。在此,我们公开了一种用于 Pd 催化和配体控制的丙二烯与亚磺酸偶联的化学发散方案,为具有共轭 ( Z,E )-1,3-的支链烯丙基砜和直链烯丙基砜提供了直接且原子经济的途径。二烯支架具有良好的收率和高选择性。该策略具有温和的条件、前所未有的底物范围和官能团兼容性。
