Method for producing seven-membered diether compounds and intermediates thereof

The invention provides a method for preparing 3,4-dihydro(2H)-1,5-benzodioxepin-3-ones represented by the formula (3): wherein R1, R2, R3 and R4 respectively represent, independently, a hydrogen atom an alkyl group or an alkenyl group, and R1, R2, R3 and R4 as a whole do not comprise more than 10 carbon atoms and that, when the two adjacent groups respectively comprise an alkyl group or an alkenyl group, they may be combined together to form a carbon ring; by reacting either a compound represented by the formula (1a) and/or (1b): wherein X represent a halogen atom; and R1, R2, R3 and R4 are as defined above; or catechols represented by the formula (5): wherein R1, R2, R3 and R4 are as defined above; with 1,3-dihaloacetones in the presence of sodium carbonate, through the removal of hydrogen halide.
