Illustrated Synthesis of MDA from Safrole


Ever wonder how NASA gets so high? This is how they make rocket fuel.

Note:

In this synthesis they achieve BLUE ketone, which is really abnormal.
Pure ketone is light yellow, but may be fluorescent greenish if prepared via Wacker oxidation of safrole /Rhodium

p-Benzoquinone Wacker oxidation and ketone purification
