An I-DMSO-mediated cascade reaction using methyl ketones and 1,2,3,4-tetrahydroisoquinolines (THIQs) as commercially available substrates has been developed for the construction of pyrrolo[2,1-]isoquinoline derivatives. This metal-free process involves N-H/α-C(sp)-H difunctionalization of THIQ. Two C-C bonds and one C-N bond are formed in one pot under mild conditions. Besides, a quaternary carbon center has been constructed in this transformation efficiently.
已开发出一种由二甲亚砜介导的级联反应,该反应使用甲基酮和1,2,3,4-四氢异喹啉(THIQs)作为市售底物来构建吡咯并[2,1 -]异喹啉衍生物。这种无金属过程涉及THIQ的N - H/α - C(sp³)-H双官能团化。在温和条件下,一锅法形成了两个C - C键和一个C - N键。此外,在该转化过程中高效构建了一个季碳中心。
