, (2020)
An efficient synthetic method was developed for the selective construction of 2H-chromene derivatives from various salicylaldehydes and acetylenic diesters using a dual catalyst system (p-toluenesulfonic acid monohydrate and pyrrolidine). The advantages of this transformation include high selectivity, good functional group tolerance, operational simplicity, and mild reaction conditions.
