A synthetic approach of isoindolinones through intramolecular amidation of ortho‐vinyl benzamides was reported. A variety of N‐aryl isoindolinone derivatives were prepared in moderate to excellent yields using perfluorobutyl iodide as oxidant.
media has emerged as a new facet of green chemistry. In this paper, a sulfone‐containing imidazolium‐based Brønsted acid ionic liquid was prepared and used as a recyclable acid catalyst. The ionic liquid catalyst enables the use of an industrially acceptable and environmentally benign solvent, butyl acetate, as the reaction medium. The ionic liquid/butyl acetate biphasic system was successfully utilized
Palladium-Catalyzed Carbonylative Synthesis of 3-Methyleneisoindolin-1-ones from Ketimines with Hexacarbonylmolybdenum(0) as the Carbon Monoxide Source
An interesting procedure for the palladium‐catalyzed carbonylativesynthesis of 3‐methyleneisoindolin‐1‐ones from ketimines was established. By using Mo(CO)6 (0.3 equiv.) as the solid CO source and through C(sp2)−H bondactivation, the desired 3‐methyleneisoindolin‐1‐ones were isolated in moderate to good yields.
Treatment of 3-hydroxyisoindolin-1-ones 1 with Lawesson reagent gave isoindoline-1-thiones 2, by direct thionation and reductive elimination of hydroxy group, in good yields.
Different Lewisacid promotor-steered highly regioselective phosphorylation of tertiary enamides with diverse H-phosphonates or H-phosphine oxides was developed. Under the catalysis of iron salt, the phosphonyl group was introduced into the α-position of tertiary enamides, affording various α-phosphorylated amides in high efficiency. On the other hand, the β-phosphorylated tertiary enamides were efficiently
