Paragraph 00272-00273, (2021/12/08)
The present application describes process for preparing an ortho-allylated hydroxy aryl compounds such as compounds of Formula (I) by reacting an allylic alcohol with a hydroxy aryl compound in the presence of aluminum compound selected from alumina and aluminum alkoxides and in a non-protic solvent wherein at least one carbon atom ortho to the hydroxy group in the hydroxy aryl compound is unsubstituted. The present application also includes compounds of Formula (I).

Unsymmetrical 1,3-diarylpropenes were synthesized in good to high yields by the palladium-catalyzed allylic arylation of allylic ethers, such as a cinnamyl phenyl ether, with a variety of arylboronic acids using a hydrazone 1a-Pd(OAc)2 system in DMAc/H2O. Using this catalyst, eugenol was also synthesized from allyl phenyl ether with (4-hydroxy-3- methoxyphenyl)boronic acid pinacol ester. A palladium-catalyzed allylic arylation of cinnamyl phenyl ether derivatives with a variety of arylboronic acids using 5 mol-% of a hydrazone 1a-Pd(OAc)2 system in DMAc/H 2O at 50 °C gave 1,3-diarylpropenes in good yields. We also succeeded with the synthesis of eugenol by a palladium-catalyzed allylic arylation. Copyright
Operationally simple and highly (E)-styrenyl-selective heck reactions of electronically nonbiased olefins

Simple, mild, and efficient conditions are reported for a Pd 0-catalyzed Heck reaction that delivers high yields and selectivity for (E)-styrenyl products using electronically nonbiased olefin substrates bearing a range of useful functionality. Preliminary mechanistic studies demonstrate that the σ-donating DMA solvent is crucial for high selectivity. Further studies suggest that the catalyst distinguishes between β-hydrogens on the basis of their relative hydridic character, in contrast to previously reported PdII-catalyzed oxidative reaction conditions.
Anti-staphylococcal activity and β-lactam resistance attenuating capacity of structural analogues of (-)-epicatechin gallate
Anderson, James C.,McCarthy, Robert A.,Paulin, Sarah,Taylor, Peter W.

We examined the impact of gradual removal of hydroxyl groups from the A- and B-rings of (-)-epicatechin gallate on antibacterial activity and oxacillin resistance attenuation of an epidemic strain of methicillin resistant Staphylococcus aureus. Removal of
