TL;DR: A tandem organosolv pulping and Pd-catalysed transfer hydrogenolysis depolymerisation and deoxygenation has been developed and generated 2,6-dimethoxy-4-(prop-1-enyl)phenol in 49% yield (92% theoretical monomer yield) starting from birch wood.
Abstract: A tandem organosolv pulping and Pd-catalysed transfer hydrogenolysis depolymerisation and deoxygenation has been developed. The tandem process generated 2-methoxy-4-(prop-1-enyl)phenol in 23 % yield (92 % theoretical monomer yield) starting from pine wood and 2,6-dimethoxy-4-(prop-1-enyl)phenol in 49 % yield (92 % theoretical monomer yield) starting from birch wood. Only endogenous hydrogen from wood was consumed, and the reaction was performed using green solvents.

TL;DR: A direct O2-coupled Pd(II)-catalyzed enantioselective dialkoxylation of 2-propenylphenols has been developed by utilizing chiral quinoline oxazoline ligands.
Abstract: A direct O2-coupled Pd(II)-catalyzed enantioselective dialkoxylation of 2-propenylphenols has been developed by utilizing chiral quinoline oxazoline ligands. A detrimental effect of added copper salts on enantioselectivity was observed which is attributed to the displacement of the chiral ligand off of Pd(II).

TL;DR: In this article, a two-step protocol for the synthesis of chiral non-racemic coumarin anticoagulants (e.g., warfarin, coumachlor and acenocoumarol) is presented.
Abstract: We have developed a general, two-step protocol for the synthesis of chiral non-racemic coumarin anticoagulants (e.g. warfarin, coumachlor and acenocoumarol). This approach features a one-pot three-component tandem Knoevenagel–hetero-Diels–Alder reaction between in situ generated 3-arylidene-2,4-chromanediones and iso -propenyl ether derived from (−)-menthol.
