Synthesis of Novel Thiazoles Based on (+)-Usnic Acid
A series of usnic acid derivatives containing a thiazole ring with an amide substituent were synthesized. The convenient method for synthesis of these compounds is a reaction of 14-bromousnic acid with N-acylthioureas. Acylation of aminothiazole does not

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(sp3)–H bond cleavage, while focusing on thiol incorporation. This method exclusively affords N,S-acetals at
