Baylis–Hillman reaction
The Baylis–Hillman reaction is a carbon-carbon bond forming reaction between the α-position of an activated alkene and an aldehyde, or generally a carbon electrophile. Employing a nucleophilic catalyst, such as tertiary amine and phosphine, this reaction provides a densely functionalized product (e.g. functionalized allyl alcohol in the case of aldehyde as the electrophile). This reaction is also known as the Morita–Baylis–Hillman reaction or MBH reaction. It is named for the Japanese chemist Ken-ichi Morita, the British chemist Anthony B. Baylis and the German chemist Melville E. D. Hillman.DABCO is one of the most frequently used tertiary amine catalysts for this reaction. In addition, nucleophilic amines such as DMAP and DBU as well as phosphines have been found to successfully catalyze this reaction.MBH reaction has several advantages as a useful synthetic method: 1) It is an atom-economic coupling of easily prepared starting materials. 2) Reaction of a pro-chiral electrophile generates a chiral center, therefore an asymmetric synthesis is possible. 3) Reaction products usually contain multiple functionalities in a proximity so that a variety of further transformations are possible. 4) It can employ a nucleophilic organo-catalytic system without the use of heavy metal under mild conditions.Several reviews have been written.
