Synthesis of Oxazolyl‐Piperidines Bearing a Quaternary Stereocenter Through a Multicomponent Reaction Involving α‐Isocyanoacetates and Piperidones

European Journal of Organic Chemistry, EarlyView.
Straightforward access to oxazole‐containing piperidines through a multicomponent reaction from α‐isocyanoacetates is described. By expanding the reactivity of these a‐isocyanoacetates from aldehydes to ketones, this process efficiently delivers oxazolyl‐piperidines bearing a quaternary stereocenter as valuable scaffolds relevant to drug discovery. The

Plasmepsins as Antimalarial Drug Targets—Then, Now, and the Future

Medicinal Research Reviews, EarlyView.
ABSTRACT Malaria is a devastating disease caused by Plasmodium parasites. Plasmodium parasites express ten cathepsin D‐like aspartyl proteases, called plasmepsins (PMs). These PMs have diverse roles fulfill diverse functions throughout the parasite's lifecycle, though several exhibit functional redundancies. Among them, PMV, PMIV, and PMX are essential

The continuing significance of chiral agrochemicals

Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Iodine-mediated ring-closing iodoamination with concomitant N-debenzylation for the asymmetric synthesis of polyhydroxylated pyrrolidines

, 2009
Treatment of a range of homochiral unsaturated β-amino esters (containing a cis-dioxolane unit) with iodine promotes a novel ring-closing alkene iodoamination reaction which proceeds with concomitant N-debenzylation, providing a simple and ...

Preclinical Evaluation of Berry Extracts as a Nutritional Intervention to Alleviate Myocardial Ischemia–Reperfusion Injury and Atherosclerosis Development

Phytotherapy Research, EarlyView.
Schematic representation of the experimental design and the proposed mechanisms underlying the cardioprotective and anti‐atherosclerotic effects of Greek‐derived berry extracts. C57BL/6 mice with WD–induced MS and ApoE−/− mice with atherosclerosis received chronic supplementation with WMex or BBex.

Radical Cyclization Approaches to Pyrrolidines

, 2002
Five-membered rings are readily prepared by 5-exo-trig radical cyclization. This thesis is concerned with novel methodology for pyrrolidine synthesis. We have synthesised selenium containing radical precursors from aziridines and α-phenylseleno ketones ...
