The reaction in which the conversion of amides to amine with one carbon atom less than the starting material in the presence of Br2 and KOH or alkaline Hypohalite is called Hoffmann rearrangement. This rearrangement was given by Agust Wilhem. Reaction : Mechanism of Hoffman Rearrangement: Step 1: Deprotonation of amide by Base (OH)…
What are terpenoids? [ez-toc] Those organic compounds which are derived from a combination of two or more isoprene units are called terpenoids. Terpenoids form naturally occurring organic compounds, most of which occur in plants and some are obtained from other sources. These are volatile compounds that give odor and fragrances to plants and flowers. They…
