disclosed. 2,5-Disubstituted pyrroles were selectively obtained in high yield with aryl alkynes and aliphatic alkynes, whereas 2,3,4-trisubstituted pyrroles were formed with silylated alkynes. This switchable method provides a controllable and facile access to both multisubstituted pyrrole scaffolds with high efficiency, excellent regioselectivity, and good functional group compatibility.
公开了具有末端炔的新颖的纳米铜催化的乙烯基叠氮化物的依赖于底物的化学发散转化。用芳基炔烃和脂族炔烃以高收率选择性地获得了2,5-二取代的吡咯,而用甲硅烷基化的炔烃形成了2,3,4-三取代的吡咯。这种可切换的方法提供了对两个多取代吡咯支架的可控且便捷的访问途径,具有高效,出色的区域选择性和良好的官能团相容性。
