This review highlights efficient synthetic methods for quinazoline derivatives using 2-azidobenzaldehyde, suggesting promising applications in drug discovery.
Quinazoline is a privileged heterocyclic scaffold commonly found in numerous pharmaceuticals and bioactive natural products, known for its diverse biological activities. The pursuit of efficient and versatile synthetic methods to produce quinazoline derivatives remains a central focus for organic and medicinal chemists, owing to the therapeutic potential of these compounds. This paper reviews the innovative use of 2-azidobenzaldehyde-enabled annulation strategies for the synthesis of quinazoline derivatives, including quinazolin-4(3H)-one, 2,3-dihydroquinazolin-4(1H)-one, 3,4-dihydroquinazoline, 3,4-dihydroquinazoline-2(1H)-thione, and 1,2,3,4-tetrahydroquinazoline. Emphasizing both the mechanistic insights and practical advantages, this review highlights the efficacy and applicability of these methods in the domain of heterocyclic chemistry, providing an invaluable framework for future drug discovery and development efforts.
