Amide-Directed Rhodium-Catalyzed Chain-Walking Hydrothiolation of Internal Alkenes.

We developed a rhodium-catalyzed chain-walking hydrothiolation process for internal alkenes, which offers a novel and efficient alternative for C(sp 3 )-H bond cleavage, while focusing on thiol incorporation. This method exclusively affords N , S -acetals at 36-90% yields. Regioconvergent hydrothiolation significantly improved the effectiveness of this transformation. Preliminary mechanistic investigations revealed that an amide-directing group is essential for regioselective synthesis, underlining its significance in this process.
