摘要： A method of reducing a C—O bond to the corresponding C—H bond in a substrate, which could be a benzylic alcohol, allylic alcohol, ester or an ether bond beta to a hydroxyl group or alpha to a carbonyl group using a recyclable metal catalyst system. The recyclable catalyst system is also applicable to reducing a C═O bond to the corresponding C—OH bond and then C—H bond. These methodologies can be linked in one-pot to selective oxidation and depolymerizations of aromatic polyols such as lignin.

摘要： The present invention relates to a process for the production of oxidized wood products, comprising step a) reacting chips of one or more wood products in a basic solution at a pH between 8 and 14 under an oxygen atmosphere at a pressure of at least 0.1 MPa, or at least 0.9 MPa. A copper catalyst may be used in the process.

摘要： A mild and efficient synthesis of primary amines and amides from aldehydes or ketones using a heterogeneous metal catalyst and amine donor is disclosed. The initial heterogeneous metal-catalyzed reaction between the carbonyl and the amine donor components is followed by the addition of a suitable acylating agent component in one-pot, thus providing a catalytic one-pot three-component synthesis of amides. Integration of enzyme catalysis allows for eco-friendly one-pot co-catalytic synthesis of amides from aldehyde and ketone substrates, respectively. The process can be applied to asymmetric synthesis or to the co-catalytic one-pot three-component synthesis of capsaicin and its analogues from vanillin or vanillyl alcohol. A co-catalytic reductive amination/dynamic kinetic resolution (dkr) relay sequence for the asymmetric synthesis of optically active amides from ketones is disclosed. Implementation of a catalytic reductive amination/kinetic resolution (kr) relay sequence produces the corresponding optically active amide product and optical active primary amine product with the opposite stereochemistry from the starting ketones.
