Dynamic Kinetic Resolution of Phthalides via Asymmetric Transfer Hydrogenation: A Strategy Constructs 1,3-Distereocentered 3-(2-Hydroxy-2-arylethyl)isobenzofuran-1(3H)-one

Dynamic kinetic resolution of phthalides through asymmetric transfer hydrogenation for the construction of 3-(2-hydroxy-2-arylethyl)isobenzofuran-1(3H)-one with 1,3-distereocenters has been developed. This procedure is carried out under a mild condition a

Practical synthesis of 3-(2-arylethylidene)isoindolin-1-ones (analogues of AKS-182) and 3-(2-arylethylidene)isobenzofuran-1(3H)-ones

A simple and practical method is reported for the synthesis of 3-(2-arylethylidene)isoindolin-1-ones and 3-(2-arylethylidene)isobenzofuran-1(3H)-ones, proceeding with good to excellent yields and (E:Z) selectivity. This methodology involves the sequential reduction-dehydration reaction of readily obtained 3-(2-oxo-2-arylethyl)isoindolin-1-ones and 3-(2-oxo-2-arylethyl)isobenzofuran-1(3H)-ones followed by a base-catalyzed double bond isomerization with K2CO3 in acetonitrile. The development of a concise synthesis of AKS-182 has been achieved using this methodology.
