Abstract

The title compounds, namely 6- methoxy- 3,3- dimethyl- 3Hbenzo[ f] chromene, C16H16O2, ( III), and racemic 3- bromo2,2,6,6- tetramethyl- 3,4- dihydro- 2H, 6H- 1,5- dioxatriphenylene, C20H21BrO2, ( IV), were both synthesized in one- step regioselective Wittig reactions from substituted 1,2- naphthoquinones. The new ring in both compounds adopts a screw- boat conformation. A single pi-pi stacking interaction links the molecules of ( III) into centrosymmetric dimeric aggregates, and a single C - H center dot center dot center dot pi( arene) hydrogen bond links the molecules of ( IV) into centrosymmetric dimers.
