The development of new methods to skeletally diverse sultams based on a central α-halo benzene sulfonamide building block is reported. Several salient features of this building block are utilized in multiple reaction pathways, including the Heck reaction, C- and O-arylation, Sonogashira-Pauson-Khand, Sonogashira-intramolecular hydroamination, lithiative cyclization and domino aza-Michael Heck for the generation of 5-, 6- and 7-membered benzofused bicyclic and tricyclic sultams.
报道了基于中心α-卤代苯磺酰胺结构单元构建多种骨架的新方法。该结构单元的几个显著特征被用于多个反应途径,包括Heck反应、碳-芳基化和氧-芳基化、Sonogashira-Pauson-Khand反应、Sonogashira-分子内氢胺化反应、锂化环化反应以及多米诺氮杂-Michael Heck反应,用于生成5、6和7元苯并稠合双环和三环磺内酰胺。
