phthalides through asymmetric transferhydrogenation 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 at 40 °C catalyzed with RuCl[(S,S)-TsDPEN](mesitylene) using HCOOH/Et3N (5:2) as a hydrogen source. A variety of phthalides are smoothly transferred to provide optically pure phthalides

A simple synthetic route affording 27%-85% yields of benzo[6,7][1,5]diazocino[2,1-a]isoindol-12(14H)-one ring systems from readily available 3-(2-oxo-2-phenylethyl) isobenzofuran-1(3H)-ones and 2-(aminomethyl)aniline starting materials in toluene and catalysed by p-toluene-sulfonic acid is developed. The ¹H- and (13)C-NMR spectra of the final products were assigned using a variety of one and two-dimensional
Design, Synthesis, and Structure‐Activity Relationship (SAR) Studies of Ketone‐Isobenzofuranone Hybrid Herbicides

Thirty-five ketone-isobenzofuranone hybrids (1–35) were designed, synthesized, and evaluated for their herbicidal activity against Chinese amaranth (Amaranthus tricolor) and barnyard grass (Echinochloa crus-galli). The structure-activity relationship (SAR) results revealed that the position and type of substituent were crucial for activity. The o-substituted derivatives outperformed the m- and p-substituted
