The synergy of the combined use of DMSO and an ionic liquid viz. (bbim)+Br- has brought about a mild, convenient, efficient, and rapid protocol for the synthesis of 1-substituted-1H-1,2,3,4-tetrazoles via the condensation of amines, triethyl orthoformate, and sodium azide at ambient temperature in excellent isolated yields (85-90%). The inherent Bronsted acidity of ionic liquid and high polarity of both IL and DMSO resulted in a significant enhancement in the reaction rate.

A facile synthesis of imidazoles and tetrazolesvia[3+1+1] type cyclization of ClCF2COONa is developed. A diverse array of imidazoles and tetrazoles were obtained in decent yieldsviaisocyanide intermediates. Notably, this is the first example of the cycloaddition ofin situgenerated isocyanides.
A stereocontrolled 1,2-addition reaction of tetrazoles with alkyl propiolates for the synthesis of highly functionalized enamines

A stereocontrolled 1,2-addition reaction of 1-aryl-1H-tetrazoles with alkyl propiolates for the synthesis of highly functionalized enamines was developed. In the presence of silver oxide (Ag2O), the 1,2-addition reaction generated (Z)-N-cyano enamines in good yields with exclusive formation of the Z-isomers. Meanwhile, the 1,2-addition reaction generated (E)-N-cyano enamines in the presence of Ag2O and potassium carbonate (K2CO 3) with high stereoselectivity and yields. Copyright
