“…In order to establish environmentally friendly chemical processes for sustainable industries, great efforts have been paid for the use of renewable sources [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15] and also for the development of a ''Green Chemical Process'', which is safer, less toxic, and an energy saving chemical process with less waste. [16][17][18][19][20][21] The utilization of heterogeneous catalysts is one of the effective approaches for both biomass conversion and green chemical processes because of easy separation from products and potentially recyclable nature. Among heterogeneous catalysts, solid acids are frequently applied for a variety of key reactions, such as hydrolysis of cellulose, [7][8][9][10][11] dehydration of saccharides, 12 acetylation, alkylation, and acylation.…”

Design of solid acid catalysts is one of the key technologies to establish environmental friendly catalytic processes. Featuring cation-exchanged clay and metal salts of heteropolyacids as model solid acid catalysts, a strategy for design of active catalysts for green chemical and biomass conversion processes is discussed. The important role of solid Lewis acids was suggested in acetylation of alcohols with acetic anhydride by cation-exchanged clay, Friedel-Crafts acylation and alkylation of aromatic compounds with metal salts of heteropolyacids, and hydrolysis of cellulose into saccharides. The significant influence of reactor design and reaction conditions on dehydration of saccharides into 5-hydroxymethylfurfural (HMF) is also discussed.

“…Therefore, most classical chemical methods applying metal catalysts are unacceptable. 25 In order to overcome the existing limitations in the currently used experimental procedures to synthesize pollutants-free peptidomimetics, a new strategy is proposed herein. For the oxidation of alcohols, enzymatic oxidation can be used, which Scheme 1 Methods used for the synthesis of peptidomimetics based on a tandem oxidation-Ugi reaction.…”
