Phenanthrene derivatives were prepared by reacting an ,-dicyanoolefin with different ,-unsaturated carbonyl compounds resulting from Wittig reaction of ninhydrin and phosphanylidene or condensation of barbituric acid and an aldehyde. The easy procedure, mild and metal-catalyst free, reaction conditions, good yields, and no need for chromatographic purifications are important features of this protocol. The structures of the product of type 3 and 5 were corroborated spectroscopically (IR, H-1- and C-13-NMR, and EI-MS). A plausible mechanism for this type of reaction is proposed (Scheme1).
