Post by: GeorgiaMJ on February 06, 2019, 07:33:23 AM

Hello,
I have trouble finding information about the dearomatization of of 5 membered heterocycles. I know the ways of dearomatization like radical, enzymatic, hydrogenation etc but I cant really find lots of dearomatization reactions. If someone could help me I would be greatful for ever ;D

You have to destroy the 4n+2 Pi electron system, some how. Means removing double bonds.

Someone on here, I think rolnor, posted a great reaction for turning thiophene into a butyl chain.
