A rapid, one-step synthesis of thieno[3,2- B]thiophene 1,1-dioxide derivatives using direct bimetalation of 3-(methylsulfonyl)thiophene and ring closure with esters is described. Two iterative, one-pot monometalations of the same substrate allowed bifunctionalization with either equal or different groups, after electrophilic quenching.
描述了使用 3-(甲基磺酰基)噻吩的直接双金属化和酯环闭合的噻吩并[3,2-B]噻吩 1,1-二氧化物衍生物的快速、一步合成。在亲电猝灭后,相同底物的两次迭代、一锅单金属化允许具有相同或不同基团的双功能化。
