Pseudodillapiole

Pseudodillapiole (4,5-dimethoxy-2,3-methylenedioxy-1-allylbenzene) is a derivative compound of allylbenzene that acts synergistically with at least some insecticides, such as piperonyl butoxide, enhancing their insecticidal effect. Pseudodillapiole can be used to synthesize a certain amphetamine derivative, 4,5-dimethoxy-2,3-methylenedioxy-1-amphetamine, also known as DMMDA-4, which is a positional isomer of DMMDA and DMMDA-2. Alexander Shulgin noted this in his book PiHKAL.
