Abstract
A brief introduction of the chemical structure and physico-chemical properties of various synthetic and naturally occurring isothiocyanates is presented. The different methods used to prepare alkyl, aryl, l-alkenyl, carbonyl, thiocarbonyl, l-aminoalkyl, aminophosphoryl and silyl isothiocyanates are systematically described. The use of the above isothiocyanates in the synthesis of thiazetidines, thiophenes, imidazoles, thiazoles, oxazoles, isothiazoles, oxathiolanes, dithiolanes, dioxolanes, triazoles, thiadiazoles, oxadiazoles, tetrazoles, thiatriazoles, pyridines, thiopyrans, oxazines, thiazines, pyrimidines, triazines, thiadiazines, oxadiazines, triazepines, benzimidazoles, benzothiazoles, quinazolones and various bicyclic and polyheterocyclic compounds with ring nitrogen and/or sulfur are reviewed.
