Here we report a mild Ag-catalyzed domino acetalization reaction using quinoline-2-carboxylates, which were substructures in a number of natural products. Methanol was directly utilized as the source of the acetal part. The main features of the domino reaction include the Minisci reaction, oxidation, and acetalization. Hydrogen fluoride generated in-situ participates in the Minisci reaction, and no external acids were needed. This domino reaction provides a simple and versatile route to heteroaromatic acetals under mild condition with good functional group tolerance using methanol.

A facile construction of quinoline-2-carboxylate esters through an aerobic oxidation of alkyl 4-anilinocrotonates is described. In the presence of dioxygen, sp3 C?H bonds in 4-anilinocrotonates can easily be oxidized by using a catalytic amount of a radical cation salt, providing a radical intermediate. After further oxidation and domino cyclization, the desired quinoline derivatives were afforded in high yields. This reaction provides a new way to construct the pharmaceutically relevant quinoline skeleton, avoiding harsh reaction conditions and tedious starting material synthesis.
Discovery and efficient synthesis of a biologically active alkaloid inspired by thiostrepton biosynthesis

Thiostrepton, a natural peptide macrocycle, is of great interest due to its structural complexity and numerous biological activities, including anti-bacterial, anti-tumor, and anti-plasmodial activities. The quinaldic acid (QA) moiety-containing side ring (loop 2) was proven to play an important role in carrying out these functions. Previously, we proposed biosynthetic logic for thiostrepton loop 2 and demonstrated the formation mechanism of QA. Herein, we report the discovery and efficient synthesis of a biologically active alkaloid, that is, a key intermediate involved in the thiostrepton biosynthetic pathway. A chemo-enzymatic method was performed to synthesize the molecule, and a series of analogs were prepared for bioassays, which included the examination of anti-bacterial and anti-tumor activities.
