Compared with conventional batch-wise process, one-pot synthesis is the “condensation” of two or more steps into one-pot
operation and increasingly used in chemical process research and development in order to achieve the desired molecular complexity in
ecologically and economically efficient way. One-pot synthesis can be achieved via multicomponent reaction (MCR), cascade reaction,
tandem reaction, or telescoping synthetic steps. This review summarizes recent progresses in this field, covering mainly four approaches
developed for the application towards one-pot organic synthesis.
