Abstract Citronellal was converted to menthol in a one-pot approach using H-Beta zeolite-based Ni catalyst batch reactor at 80 °C, under 20 bar of total pressure. The effects acidity (H-Beta-25 with the molar ratio SiO 2 /Al O 3 = 25 and H-Beta-300 300) loading (5, 10 15 wt %) on catalytic performance were investigated. impregnated support evaporation-impregnation method. physico-chemical prope...

Bacterial resistance has been increasingly reported worldwide and is one of the major causes of failure in the treatment of infectious diseases. Natural-based products, including plant secondary metabolites (phytochemicals), may be used to surpass or reduce this problem. The objective of this study was to determine the antibacterial effect and mode of action of selected essential oils (EOs) com...

A concise, protecting group-free total synthesis of (-)-fusarisetin A (1) was efficiently achieved in nine steps from commercially available (S)-(-)-citronellal. The synthetic approach was inspired by our proposed biosynthesis of 1. Key transformations of our strategy include a facile construction of the decalin moiety that is produced via a stereoselective IMDA reaction and a one-pot TEMPO-ind...

A new nanocatalyst which comprises gold particles (average size = (2.5 ± 1.3) nm) supported on intrinsically conductive polyaniline (PANI) was prepared via a sol-method. This Au/PANI catalyst was used for the first time in hydrogenation of the , -unsaturated aldehyde citral exhibiting high activity (93% conversion) and selectivity (76%) towards the products of C=O group hydrogenation, geraniol ...
