The direct one-pot reductive imination of nitroarenes with various aldehydes by a titania supportedgoldcatalyst at room temperature using CO/H2O as a reducing agent is illustrated. This method is simple, economic, general and environmentally benign, thus resulting in practical advantages for the synthesis of imines and their derivatives.

delivery to a specific pH window. Specifically, we utilize self-immolative thiocarbamates with an imine-derived triggering group. After imine hydrolysis, the self-immolative decomposition releases carbonyl sulfide (COS), which is quickly hydrolyzed to H2S by carbonic anhydrase. Although acid-mediated hydrolysis results in imine cleavage, environments that are too acidic result in protonation of the aniline
benzoic imine chemistry. As a proof-of-concept investigation of the approach, a well-defined poly(ethylene glycol)-based SRD-ABP containing conjugated benzoic imine pendants in the hydrophobic block was synthesized by a combination of reversible deactivation radical polymerization and postpolymerizationmodification. The synthesized copolymer self-assembled in an aqueous solution to form colloidally stable

A number of novel acid-sensitive Schiff bases derived horn p-aminobenzyl alcohol and various benzaldehyde derivatives were synthesized and were subsequently shown to trigger benzyl elimination reactions The kinetics of acid-catalyzed hydiolysis at pH 50 as well as stability at pH 74 were studied using fluorogenic model compounds Two fluoro-substituted Schiff bases showed efficient hydrolysis at pH 5 0 combined with a long-term stability at pH 74 and are considered suitable candidates for the development of anticancer prodrugs (c) 2010 Elsevier Ltd All lights reserved
