ABSTRACT |
|
|
|
A mild and efficient method was
developed for the synthesis of benzopyrans through the one-pot
three-component condensation of aldehyde, malononitriles, and
dimedone in the presence of polyethylene glycol-400 as an efficient
and recyclable reaction medium. This process is characterized by
mild reaction condition, easy workup, and environmental
friendliness.
