Green chemistry methods: Synthesis of bioactive molecules-based quinazoline, quinoline, quinoxaline, benzimidazole and imidazole

The destruction of the ecosystem caused by chemicals such as pesticides, fertilizers, plastics, and greenhouse gases has provoked the conscience of the public and regulators to control the use of chemicals. There is a growing concern and awareness about preserving the environment against the danger of toxic substances. Sustainable industrial development as a means of cutting pollution from industry and developing renewable raw materials for industry has been a challenge in the twenty-first century. This review outlines the basics and ideas of green chemistry with examples and emphasis on the synthesis of bioactive molecules—based quinazoline, quinoline, quinoxaline, benzimidazole and imidazole from 2012 to 2025 to illustrate different fronts for developmental improvement in achieving sustainable procedures.
