Recent Advances in the Baylis−Hillman Reaction and Applications
Journal ArticleDOI
Acceleration of the DABCO-promoted Baylis–Hillman reaction using a recoverable H-bonding organocatalyst ☆
TL;DR: It has been shown that catalytic amounts of bis-aryl (thio)ureas greatly accelerate the DABCO-promoted Baylis–Hillman reaction between a range of aromatic aldehydes and methyl acrylate in the absence of solvent.

Lewis base and L-proline co-catalyzed Baylis-Hillman reaction of arylaldehydes with methyl vinyl ketone
TL;DR: In this article, the Baylis-Hillman reaction of arylaldehydes with methyl vinyl ketone was investigated in the presence of a catalytic amount of l -proline, weak bases such as imidazole and triethylamine as well as the stronger Lewis base DABCO.

Ionic liquids as a recyclable reaction medium for the Baylis–Hillman reaction
TL;DR: The Baylis-Hillman reaction using 1,4-diazabicyclo[2.2] octane (DABCO) has been shown to be 33.6 times faster in the recyclable ionic liquid 1-n-butyl-3-methylimidazolium hexafluorophosphate ([bmim][PF6]) than in acetonitrile as discussed by the authors.

TiCl4-Mediated Baylis–Hillman and aldol reactions without the direct use of a Lewis base
TL;DR: TiCl4-Mediated Baylis–Hillman and aldol reactions were developed without the direct use of a Lewis base by the conjugate addition of TiCl4 to α,β-unsaturated substrates followed by carbonyl coupling.

The baylis-hillman reaction : a novel carbon-carbon bond forming reaction
TL;DR: In this paper, an approach to chiral Baylis-hillman adducts is presented. But it does not address the problem of chiral activation and self-dimerization of alkenes.
