The ongoing study is a Ugi-azide four-component reaction for the synthesis of 1,5-disubstituted tetrazole(1,5-DST), which involves an aldehyde, different amines, isocyanides, and as azide’s source the Trimethylsilylazide (TMSN3), in water as solvent using as catalyst the tetradecyltrimethylammonium bromide (TTAB) with a load of (10% mole), which provides a hydrophobic micellar reaction site. This approach is a step toward a green chemistry reaction of 1,5 disubstituted tetrazole. A serie of 1, 5- disubstituted tetrazole was synthesized by engaging a large substrate scope, leading to yields between 43% and 56%, which are compared afterwards with those obtained with methanol as solvent. The results were confirmed by HRMS, IR, and 1D NMR experiments.

Component Approach

A one-pot three-component reaction promoted by choline chloride: zinc(II) chloride deepeutectic solvent (ChCl-ZnCl2 DES) in an aqueous medium for the synthesis of several merocyanin dyes based on isoxazol-5(4H)-ones is presented. This three-component approach is efficient, clean, experimentally simple, convenient, safe, and environmentally friendly. This reaction was performed at room temperature without using energy sources such as heat, microwave and ultrasound waves. Nonuse of toxic solvents, available materials, one-vessel, no wasted reagents, simple preparation, and recyclability of DES are other important points of this method that is significant from the perspective of green chemistry.

Work Up

We report an enantioselective Henry (nitroaldol) reaction catalysed by an organocatalyst using water as solvent. The enantioselective synthesis of β-nitroalcohols was achieved by using a neutral chiral organocatalyst, through strong hydrogen bonding, which results in the formation of corresponding products in excellent yield and enantioselectivity at room temperature. Other attractive features of the method are the eco-friendly, non-hazardous, and mild reaction conditions, inexpensive catalyst, and simple work up conditions.
