Diels−Alder reactions with dienophiles, compounds 1 behaved like reactive dienes, adding at positions 8 and 11 of the aromatic ring. Substitution by chlorine, though, reduced the reaction rate; the unsymmetrical dienophile acrylonitrile showed little preference for the two possible regioisomeric adducts 8 and 9. Similarly, compounds 1 were unusually reactive towards acid, and interesting and unforeseen
