Integrating Visible‐Light Photocatalysis and Enzymes for the Stereoselective Synthesis of Alcohols and Amines

Advanced Synthesis &Catalysis, EarlyView.
The integration between visible‐light photocatalysis and biocatalysis has the potential to greatly improve modern organic synthesis by combining the production of valuable synthetic intermediates under mild photochemical conditions with the high degree of stereoselectivity reached by enzymes. The review collects the recent efforts in the photoenzymatic

Challenges in agrochemicals design [PDF]

Journal of Cheminformatics, 2013
Design of active ingredients is a multidimensional task. Sufficient target activity in combination with high bioavailability and no (or at least low) toxicological behaviour are prerequisites for promising candidates. In this respect, pharmaceutical and agrochemical companies need to address the same issues.

Assembling Hexahedral Supramolecular Nano‐Aggregates on Rice Wax Layer Matrices to Promote the Leaf Deposition and Bioavailability of Bactericides for Plant Protections

Advanced Science, EarlyView.
To address the problem of off‐target movement and low bioavailability of pesticides, two anisotropic supramolecular building units (BiTA18@β‐CD and BiTA18@γ‐CD) have been invented that can self‐assemble into nano‐sized hexagonal cuboids on the rice microcrystalline matrix. This manipulation realizes the enhanced utilization of bactericides for rice and

Engineered C–N Lyases for Stereoselective Synthesis of Tertiary Amines

Angewandte Chemie, EarlyView.
EDDS lyase was subjected to iterative cycles of site‐saturation mutagenesis and screened for increased activity for the addition of 2‐((methylamino)methyl)aniline to fumarate. The final mutant, EDDS lyase CEA, accepts various N‐methyl‐1‐phenylmethanamines derivatives, yielding N,N‐disubstituted L‐aspartic acids, as well as several ortho‐substituted ...
