Advanced Science, EarlyView.The diagram illustrates a sustainable model of lignin valorization and carbon cycling based on microbial cell factories. Using lignin as the feedstock, synthetic biology technologies, including depolymerization, cell factory construction, pathway gene module integration, and metabolic network regulation, are applied to convert lignin into bulk ...

Rational Design of π‐Conjugated Polymers for Enantioselective Recognition of Amino Acids
Advanced Electronic Materials, EarlyView.A family of conducting polymers is proposed for the enantioselective recognition of amino acids. The films are generated by electropolymerization of thiophene trimers containing chiral features, with the advantage that the polymerization can be induced at much lower overpotentials compared to classic thiophene monomers, thus avoiding parasitic ...

Enantioselective semireduction of allenes [PDF]
Nature Communications, 2017 AbstractRh-hydride catalysis solves a synthetic challenge by affording the enantioselective reduction of allenes, thereby yielding access to motifs commonly used in medicinal chemistry. A designer Josiphos ligand promotes the generation of chiral benzylic isomers, when combined with a Hantzsch ester as the reductant.

Inter- and intramolecular enantioselective carbolithiation reactions
Beilstein Journal of Organic Chemistry, 2013 In this review we summarize recent developments in inter- and intramolecular enantioselective carbolithiation reactions carried out in the presence of a chiral ligand for lithium, such as (−)-sparteine, to promote facial selection on a C=C bond.
