Synthesis of 1, 8-Dioxa-dibenzo[e, h]azulenes

A novel synthetic route to 2-methyl-1, 8-dioxa-dibenzo[e, h]azulenes via cyclisation of the corresponding 1, 4-dicarbonyl compound is described. 1, 4-Dicarbonyl compounds were synthesized by the alkylation reaction of the 11H-dibenzo[b, f]oxepine-10-one while analogous alkylation of 11H-dibenzo[b, f]thiepine-10-one resulted in formation of O-alkylated products. Selective oxidation of 2-methyl group afforded 1, 8-dioxa-dibenzo[e, h]azulenes with formyl and hydroxymethyl functionality at C(2) position.
