Ionic liquids as a recyclable reaction medium for the Baylis-Hillman reaction
Rosa, Jo?o N,Afonso, Carlos A.M,Santos, António G
, p. 4189 - 4193 (2001)
The Baylis-Hillman reaction using 1,4-diazabicyclo[2.2.2]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. Low yields (14-2
Synthesis and characterization of chiral enantiopure bis-chromanones: a Baylis-Hillman approach
Rajan, Yeasudhasan Christu,Kanakam, Charles Christopher
, p. 3023 - 3026 (2008)
Enantiopure bis-chromanones were prepared from (S)-Binol and bromo esters via a Baylis-Hillman approach. Chiroptical studies indicate that the two-naphthyl units of the chromanone system are non-coplanar.
Microwave-Assisted 1,3-Dioxa-[3,3]-Sigmatropic Rearrangement of Substituted Allylic Carbamates: Application to the Synthesis of Novel 1,3-Oxazine-2,4-dione Derivatives

In a first instance, the effect of the microwave irradiation on the 1,3-Dioxa-[3,3]-sigmatropic rearrangement of aryl allylic carbamates was investigated. Under these new conditions, the reaction acceleration was clearly highlighted compared to convention
Phosphine-Catalyzed [3 + 2] Annulation of Morita-Baylis-Hillman Carbonates with Isoxazole-Based Alkenes

A phosphine-catalyzed [3 + 2] annulation of Morita-Baylis-Hillman (MBH) carbonates with 3-methyl-4-nitro-5-styrylisoxazoles has been developed to afford various multifunctional isoxazoles in moderate to good yields with moderate to excellent diastereoselectivities. With a spirocyclic chiral phosphine as the catalyst, up to 89% ee was obtained.
