Reaction of 2-acetoxy-3-chloro naphthoquinones towards the 1,3-dioxy diene (2) and the 1,1,3-trioxy diene (9) was examined. The competing influence of the acetoxy and chloro substituents was assessed from the regiochemistry of the resulting Diels–Alder chemistry, as was competition between that process and Michael addition/elimination. Reaction of the same dienes towards the less reactive 2,3-diacetoxy naphthoquinone (25) was also investigated.
