How to use isosafrole to indirectly synthesize piperonyl methyl ketone CAS 28578-16-7?

Indirect Synthesis of Isosafrole

French Gimeno et al. obtained a pale yellow oily piperonyl methyl ketone CAS 28578-16-7 by oxidizing isosafrole with hydrogen peroxide in a formic acid medium, and then dehydrating the glycol with sulfuric acid.

How to synthesize piperonyl methyl ketone CAS 28578-16-7 PMK oil from piperonal?

Piperonal is also known as jasmine aldehyde, and its chemical name is 3,4-methylenedioxybenzaldehyde. The synthesis process using piperonal as a raw material has simple raw materials, no large amount of waste gas and waste liquid are discharged during the synthesis process, and is environmentally friendly. The research draws the synthetic route of obtaining piperonyl methyl ketone CAS 28578-16-7 with piperonal as raw material:

In the first step reaction, ammonium acetate is used as a catalyst and glacial acetic acid is used as a solvent to obtain β-nitroisosafrole.

In the second step reaction, reduced iron powder is used as a catalyst. In the reaction process, the amount of hydrochloric acid is different, and the products of the reaction are also different: one is ketoxime, and the other is ketone. Therefore, the amount of hydrochloric acid should be controlled.

What other roles of piperonyl methyl ketone CAS 28578-16-7 PMK oil in the synthesis?

Most routes for the synthesis of 3,4-methylenedioxymethamphetamine (MDMA) start from compounds containing a 3,4-methylenedioxyphenyl ring, such as safrole, isosafrole, piperonal, Bromosafrole and piperonyl methyl ketone CAS 28578-16-7 (PMK oil) etc. PMK is currently the most important precursor compound for the synthesis of MDMA in underground processing plants, and MDMA can be prepared by a simple Lukat method or a reductive amination method.
