“…Proper knowledge of reaction mechanisms guides the development of rationally designed catalysts, appropriate stereochemical control, and the elaboration of efficient synthesis of new molecules, especially those with biological and/or technological interest. The Morita–Baylis–Hillman (MBH) reaction provides an elegant and efficient route to generate new σ C–C bonds yielding α-methylene-β-hydroxy derivatives. The MBH reaction has been known for a long time, but it is currently experiencing a return to prominence due to recent improvements in the experimental conditions and catalysts leading to higher yields and selectivities. …”

“…The Baylis−Hillman (BH) reaction is one of the most studied reactions in the last couple of years . The synthetic utility of this carbon−carbon bond-forming reaction has been exploited both in solution and solid phase 31 chemistry, since it offers a convenient route toward generation of array of multifunctional products, which can be selectively extended further. These products have also been utilized as the building blocks for natural products and biologically active compounds .…”

“…Hz, atribuído ao hidrogênio da hidroxila, integrando para 1 hidrogênio. Continuando, em 5,50 ppm, encontra-se outro dupleto largo com constante de acoplamento de 6,0 Hz, atribuído ao hidrogênio carbinólico(8), integrando para 1 hidrogênio, sinal característico de formação do aduto. Os hidrogênios vinílicos são observados em 5,72 ppm e 6,25 ppm, um tripleto aparente, com J de 1,2 Hz e um multipleto respectivamente, ambos integrando para 1 hidrogênio.…”
