• Ozonolysis of α-dihydrosantonin B (3) and santonin α-oxide (1) gave δ-lactol type compounds (4) and (11), respectively. (4) gave δ-lactol methyl ether (6) on treatment with diazomethan while it produced an aldehyde ester (9) with methyl iodide. On the contrary, the aldehyde ester (13) was obtained on treatment of (11) with diazomethane or methyliodide. (15) derived from (4) under acid or alkali conditions afforded a new lactone (17) due to the cyclohexane ring inversion and the lactone ring reclosure in (15). (4) and (11) transformed on treatment with to benzimidazoline derivatives (30) and (32), respectively, as well as with ethylenediamine to the imidazolidines of (34) and (36), respectively.
