Abstract

Thiadiazole moieties are present in many natural products and pharmaceutical compounds that possess a broad spectrum of biological activities, serving as antidepressant, anxiolytic, antimicrobial, antitubercular, antiinflammatory, antidiabetic, anticancer, antihypertensive, or antifungal drugs. Many excellent methods have been reported for accessing such frameworks. In this review, we summarize advances made within the past ten years in the synthesis of various types of thiadiazole.
