The Petasis reaction

The Petasis reaction can be viewed as a boronic acid equivalent of the Mannich reaction, and is often used as an alternative to the reductive amination reaction.

Applications

[edit]

In one application the Petasis reaction is used for quick access to a multifunctional scaffold for divergent synthesis.[4][5]
