A deep eutectic solvent of glucose-urea was found to be an inexpensive and effective reaction medium in the synthesis of piperidin-4-one derivatives. In this work, 3-methyl-2,6-diphenyl piperidin-4-one (4a), 3,5-dimethyl-2,6-diphenylpiperidin-4-one (4b), 2,6-diphenylpiperidin-4-one (4c), piperidin-4-one (4d), 3,5-dimethylpiperidin-4-one (4e), 3-methyl-2,6-di(2-hydroxyphenyl)piperidin-4-one (4f), 3,5-dimethyl 2,6-di(2-hydroxyphenyl)piperidin-4one (4g) were synthesized using a deep eutectic solvent (DES) of glucose and urea with the percentage composition of 60:40. The yields of these products were 82, 78, 75, 68, 72, 70 and 70 %, respectively. The products obtained were characterized by FT-IR and 1H NMR spectroscopic techniques. A synthesis of piperidin-4-one derivatives by using this green solvent was considered to be new environmentally safe synthetic method.

A series of tosyl carbamates have been synthesized and screened for their antibacterial and antifungal activities. All the synthesized compounds were characterized by spectral techniques (IR, 1H, 13C NMR and mass) and elemental analysis. in silico Molecular docking method was performed to study their antimicrobial activity against the target protein 1T9U. Compound 27 showed good antibacterial activity against Gram-positive and Gram-negative bacterial strains and compound 19 showed good antifungal activity. Molecular docking results revealed that the compound 19 exhibits minimum CDOCKER energy. Tosyl carbamate derivatives having good antimicrobial activities compared to that standard and all the synthesized compounds exhibits moderate CDOCKER scores.
