Asymmetric radical carboesterification of dienes

open access: yesNature Communications, 2021
Stereocontrol of C–O bond formation from a carbon-based radical is very difficult due to the rapid inversion of the carbon radical. Here the authors present a method to form chiral esters from conjugated dienes with copper and chiral PyBox ligands ...

Easy access to medium-sized lactones through metal carbene migratory insertion enabled 1,4-palladium shift

open access: yesNature Communications, 2020
Transannular construction of medium-sized lactones is entropically unfavoured. Herein, the authors describe a strategy for valuable medium-sized lactone synthesis from available benzaldehydes by selective C-H bond functionalization via palladium carbene ...

Cadmium-induced ethylene production and responses in Arabidopsis thaliana rely on ACS2 and ACS6 gene expression [PDF]

open access: yes, 2014
Background: Anthropogenic activities cause metal pollution worldwide. Plants can absorb and accumulate these metals through their root system, inducing stress as a result of excess metal concentrations inside the plant.

VvERF111 Regulates Chlorophyll Degradation by Activating Expression of VvCLH1, Leading to Rachis Browning in Grape

open access: yesHorticulturae, 2023
The plant growth regulator ethylene influences rachis browning in grape (Vitis vinifera L.). Although the ethylene signaling pathway is well defined, there is limited knowledge on its mode of action during rachis browning.
