Abstract

GRAPHICAL ABSTRACT: Abstract: A convenient one-pot synthesis of chromene derivatives from the three-component reaction of triphenylphosphine and dialkyl acetylenedicarboxylate and 2-hydroxybenzaldehyde derivatives in the presence of ß-cyclodextrin as a nano-catalyst is reported. In this reaction, ß-cyclodextrin (4.5 mole%) acts as a nano-catalyst as well as nano-reactor. This methodology is of interest due to the use of water in the presence of "ß-cyclodextrin nano-reactor" as a green reaction system.
