Abstract Nitrogen‐containing heterocycles such as imidazoles, thiazoles, and oxazoles play a significant role in the fields of biological pharmaceutical chemistry. These compounds were widely used for agrochemical, pesticide, medicinal, industrial applications. Due to wide spectrum structural diversity well activity N ‐heterocycles, plethora reports on their synthesis have appeared last few decades. However, developments various bond‐forming strategies C−C, C−N, C−O, C−S, N−N, C−H activation, been powerful synthetic tool derive copious ‐heterocycles. The most prominent fascinating imidazole, thiazole, oxazoles, benzimidazole moieties by C−C C−N coupling reactions, multi‐component cycloaddition etc. are discussed this study. studies demonstrated enormous potential methods accelerating modern chemical establishing molecular beauty through bonding. aspects methodologies, like optimized conditions, substrate scope, mechanistic investigations, detail.
