This rather green and leafy cover image is courtesy of Kazuya Kikuchi and co-workers at Osaka University who have developed a new mechanism for a reversible dual “OFF–ON–OFF” pH sensor with the influence from a suitably located carboxylic acid group.
pH Induced dual “OFF–ON–OFF” switch: influence of a suitably placed carboxylic acid

Highlighted on the inside cover of this issue is the work of J. Carlos Menéndez and colleagues who have developed an efficient method for the synthesis of trans-2-aryl-4-arylamino-tetrahydroquinolines from 3,5-disubstituted anilines, vinyl ethers and aromatic aldehydes.
Diastereoselective, multicomponent access to trans-2-aryl-4-arylamino-1,2,3,4-tetrahydroquinolines via an AA′BC sequential four-component reaction and their application to 2-arylquinoline synthesis
Pascual Ribelles, Vellaisamy Sridharan, Mercedes Villacampa, Mª Teresa Ramos and J. Carlos Menéndez
