Relevant Developments in the Use of Three‐Component Reactions for the Total Synthesis of Natural Products. The last 15 Years

ChemistryOpen, Volume 13, Issue 5, May 2024.
Multicomponent reactions (MCRs) are a valuable strategy toward complex polysubstituted compounds because they simplify long sequences, increasing their efficiency. The total synthesis of natural products achieved since 2004 through the use of three‐component reactions as a strategic MCR approach is reviewed.

Alternaria diseases on potato and tomato

Molecular Plant Pathology, Volume 25, Issue 3, March 2024.
We review the major Alternaria species that cause early blight disease complex (genetic diversity, genome structure and mechanisms of pathogenicity), management strategies such as resistance breeding and fungicide resistance. Abstract Alternaria spp. cause different diseases in potato and tomato crops. Early blight caused by Alternaria solani and brown
