One-Pot Multicomponent Synthesis of Thiourea Derivatives in Cyclotriphosphazenes Moieties

In this study, hexasubstituted thiourea was carried out via reaction of isothiocyanato cyclophosphazene intermediates with a series of aromatics amines and amino acids in a one-pot reaction system. The reaction was not as straightforward as typical thiourea synthesis. Six unexpected thiourea derivat...

description In this study, hexasubstituted thiourea was carried out via reaction of isothiocyanato cyclophosphazene intermediates with a series of aromatics amines and amino acids in a one-pot reaction system. The reaction was not as straightforward as typical thiourea synthesis. Six unexpected thiourea derivatives 3a-f were formed in the presence of cyclotriphosphazene moieties in good yields (53-82%). The structures of 3a-f were characterized by elemental analysis and FTIR, 1H, 13C, and 31P NMR spectroscopies. The occurrence of reverse thioureas formation in a one-pot reaction system is discussed. The possible binding interaction of the synthesised thiourea 3a-b in comparison to the predicted phenyl thiourea 5a-b and the targeted 4a with enzyme enoyl ACP reductase (FabI) is also discussed. Molecular docking of the targeted hexasubstituted thiourea 4a is able to give higher binding affinity of -7.5 kcal/mol compared to 5a-b (-5.9 kcal/mol and -6.3 kcal/mol) and thiourea 3a-b (-4.5 kcal/mol and -4.7 Kcal/mol). © 2017 Zainab Ngaini et al.
