Abstract
Phytoalexins are induced chemical defenses produced by plants in response to diverse forms of stress, including microbial attack. Although phytoalexins from over 30 different plant families have been isolated since Müller first proposed this term in 1940, crucifers were the first plants reported to produce phytoalexins containing sulfur and nitrogen. Most of the cruciferous phytoalexins are biogenetically derived from tryptophan but have rather different chemical structures as well as biological activities. The relatively large amounts of phytoalexins currently required for a diversity of chemical and biological studies are usually obtainable through synthesis, as isolation from plants is difficult and very time consuming. Herein we review work reporting the chemical structures, syntheses, and biosyntheses of cruciferous phytoalexins and present new perspectives on the potential applications of these compounds and analogs.

Advances of Heterocyclic Chemistry with Pesticide Activity
Global food safety and security will continue to be a global concern for the next 50 years and beyond. Plant diseases have had a significant impact on food safety and security throughout the entire food chain, from primary production to consumption. While conventional chemical pesticides have been traditionally used for ...read more
Calculation design of covalent/metal organic framework based catalysts
This research area combines theoretical computation and screening with machine learning for the design of covalent/metal organic framework-based catalysts, bridging the disciplines of organic chemistry, physical chemistry, computational chemistry, materials science, and machine learning. It covers several critical aspects: designing and synthesizing organic catalysts for improved performance, applying computational methods ...read more
Carbohydrates conversion in biofuels and bioproducts
Biomass pretreatment, hydrolysis, and saccharification of carbohydrates, and sugars bioconversion in biofuels and bioproducts within a biorefinery framework. Carbohydrates derived from woody biomass, agricultural wastes, algae, sewage sludge, or any other lignocellulosic feedstock are included in this issue. Simulation, techno-economic analysis, and life cycle analysis of a biorefinery process are ...read more
Catalytic C-H bond activation as a tool for functionalization of heterocycles
The major topic is the functionalization of heterocycles through catalyzed C-H bond activation. The strategies based on C-H activation not only provide straightforward formation of C-C or C-X bonds but, more importantly, allow for the avoidance of pre-functionalization of one or two of the cross-coupling partners. The beneficial impact of ...read more
