A pyrrolidine-mediated Knoevenagel-type reaction for highly stereoselective construction of novel α-halo-1,3-dienylsulfonyl fluorides was achieved in up to 100% Z-selectivity and high yields at room temperature from condensation of the readily available aldehydes and halomethanesulfonyl fluorides. This protocol provided a class of unique α-halo-1,3-dienylsulfonyl fluorides with wide scope and excellent
吡咯烷介导的Knoevenagel型反应可实现高度立体选择性地构建新型α-卤代1,3,2-二烯基磺酰氟,在室温下通过易得的醛类和卤代甲磺酰氟的缩合可实现高达100%的Z选择性和高收率。 。该方案提供了一类独特的α-卤代-1,3-二烯基磺酰氟,具有宽范围和出色的官能团相容性。α-卤代1,,3-二烯基磺酰氟被用作氟化硫交换点击化学,Suzuki反应和Sonogashira反应中的通用构件,用于组装高度官能化的二烯基磺酰氟衍生物,用作共价战斗部以发现新药。
