« on: February 06, 2019, 01:33:23 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
