The cover picture shows a new and green transformation path for the synthesis of γ-valerolactone from biomass-derived ethyl levulinate, which is realized by iron-catalyzed transfer hydrogenation. γ-Valerolactone is a valuable chemical, which can be used as liquid fuel, food additive, solvent and also intermediate for organic synthesis. By utilizing Casey's catalyst and cheap isopropanol as hydrogen source, γ-valerolactone can be generated in 95% yield. Addition of catalytic amount of base is important to achieve good yield. More details are discussed in the communication by Fu et al. on page 405–408.

Two series of tetrahydroisoindoline-1,3-diones containing an alkoxycarbonyl substituted 2-benzoxazolinone moiety were designed and synthesized. Compound 1h displayed excellent herbicidal effect against Abutilon theophrasti with ED50 values of 1.8 g AI·ha−1, and compound 1h could potentially be used as a new post-emergence herbicide for maize fields.
