N-N bond bearing organic frameworks such as azo, hydrazine, indazole, triazole and their structural moiety has piqued the interest of organic chemist due to intrinsic nitrogen electro negativity. Recent methodologies...
Bio‐catalysis is a versatile and powerful tool in organic synthesis, hazardous chemical remediation, biosensors, and industrial sectors. It has been claimed that laccases can function as an intriguing class of biocatalyst in organic chemistry. They are highly favourable catalysts and offer advantages over conventional oxidants and toxic metal catalysts by exhibiting high activity in aqueous media under mild conditions and also work on diverse functional groups possessing substrates maintaining the atom economy. They coordinate well with molecular oxygen and perform chemo selective oxidation reactions, as well as a plethora of other reactions. However, this review is intended to cover molecular oxygen‐assisted laccase catalysis in organic transformations and its significance in industry.
Of late, regio-selective tandem reactions are given much attention due to the formation of several multiple bonds in a single synthetic operation, avoids altering the reaction conditions, isolation of the intermediates during the reaction, reduces the production of toxic waste to the environment and can produce highly complex organic molecules with desired selectivity. Though, it requires the well-built knowledge for optimization of the process, it permits to make the complex organic molecules with least number of steps, and it has eventually made great interest and inspiration to the upcoming organic chemists. Presentation of current book chapter presents the Cu-Catalysed tandem reactions for building poly hetero atom heterocyclic compounds via green approach.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
