The oxidative intramolecular tandem cyclization of 4,4-diaryl-3-butenyl 3-oxobutanoates 3a-e and 4,4-diaryl-3-butenyl 2-(2-aryl-2-oxoethyl)-3-oxobutanoates 5aa-ee using manganese(III) acetate was investigated. The reaction of oxobutanoates 3a-e gave the desired dual cyclization products, 7,7-diaryl-9-methyl-3,8-dioxabicyclo[4.3.0]non-9-en-2-ones 4a-e, in excellent yields. A similar cyclization of oxobutanoates 5aa-ee did not give the tricyclic compounds 7 but 1-acetyl-7,7,9-triaryl-3,8-dioxabicyclo[4.4.0]dec-9-en-2-one 6aa-ee in good yields.
