The interaction of 10-iminophenanthrene-9(10)-one and 3-furan-2-yl-propenal in ethanol synthesized 2-(2-(furan-2-yl)vinyl)phenanthro9,10-oxazole. Electrophilic substitution reactions of this compound (nitration, bromination, sulfonation, formylation, acylation) were investigated. Under the conditions of the studied reactions, the 5-position of the furan core is substituted.
