Synthesis and Insecticidal Activity of Lignan Analogs (III).
Ten haedoxan analogs with the bond split between 2C and 3C of the 6-methoxy-2-methoxymethyl-3-(3,4-methylenedioxy)phenyl-1,4-benzodioxan-7-yl group of haedoxans were synthesized, and their insecticidal activity was assessed on the housefly. The inactivity of an analog having a 2-methoxy-5-(2-methoxyethoxy)-4-(3,4-methylenedioxybenzyloxy)phenyI instead of the 1,4-benzodioxan-7-yl group made it evident that the benzodioxane framework is essential for the activity of haedoxans.
