Spiroacenaphthylene derivatives

A variety of substituted spiroacenaphthylene derivatives 39 were also synthesized in water from the one-pot multicomponent reaction of acenaphthenequinone (24), cyclic 1,3-diketone, and malononitrile/ethyl cyanoacetate 3 in the presence or absence of catalysts under reflux conditions (Scheme 21) [118,120,122,123].
