Abstract
ABSTRACT Ethylenediamine diacetate is found to be an efficient catalyst for the multicomponent condensation reaction of dimedone, aldehydes, and malononitrile to afford the corresponding tetrahydrobenzo[b]pyrans in good yields. The remarkable features of this new procedure are high yields, short reaction times, simple experimental and work-up procedures, mild and environmentally friendly reaction conditions, and economic availability of the catalyst.
