We observed intriguing substituent effects in the reaction between 4-substituted acetophenones and acenaphthenequinone in the presence of KOH in methanol. In all cases, expected Claisen-Schimdt condensation was the first step. However, depending on t

A Michael-aldol domino reaction sequence of acenaphthenequinone with acetophenone in the presence of KOH in methanol solvent leading to the formation of three different 2:2 adducts arising through three distinct reaction sequences is described. Simil

A number of new 3,3-dimethoxy-2-aryl-2,3-dihydro-1-oxacyclopenta[l]phenanthren-2-ols were synthesized by the base-catalyzed reaction between phenanthrenequinone and 4-substituted acetophenones in methanol. These furanols are unstable and are easily c

Irradiation of 3-methoxy-3-aryl-3H-1-oxacyclopenta[l]phenanthren-2-one derivatives 5a–d resulted in singlet-mediated decarbonylation reaction leading to the formation of phenanthrene derivatives 9a–d. The structure of the photoproduct was unequiv
