Benzodioxole chemistry. 5.1 Dramatic substituent effect in the reaction of carbonyl-bridged cyclic carbonates with methoxide ion

Benzodioxolediones (2c-e) undergo high-yield conversion to cyclopentenones (3c-e) in K2CO3/MeOH at room temperature, while analogs (2a) and (2b) yield exclusively cyclohexadiene carboxylates (1a and 1b) under these conditions. Isolation of intermediate 6(R,R′=Me R″=Ph) from the reaction of 2c with K2CO3/MeOH at 5-10°C suggests that 3 is formed in a process triggered by attack of OMe(-) at the ester carbonyl of 2.
