Stork enamine reaction: Promising Mechanism with application

Stork enamine reaction, examples, mechanism, and its application have been discussed here. Stork enamine reaction was first of all reported by Stork in 1954.

stork enamine reaction

Stork enamine reaction is the alkylation of cyclic ketone in presence of pyrrolidine via the formation of enamine as an intermediate. When cyclic ketone reacts with pyrrolidine gives enamine which reacts with alkyl halide followed by hydrolysis generates alkylated cyclic ketone.

stork enamine reaction mechanism

The mechanism of stork enamine reaction can be explained in the following steps.

Step 1: The lone pair of electrons of present on the N-atom of pyrrolidine attacks the carbonyl carbon of cyclic ketone, and forms enamine.
