Abstract:
MitoNEET (CISD1), an [2Fe-2S] cluster protein located on the outer mitochondrial membrane and known for its role in cellular redox regulation and bioenergetics, has been identified as a novel ferroptosis-related drug target in neurodegeneration and cancer. The mitoNEET ligand NEET ligand-1 (NL-1) was developed as a pharmacological tool to elucidate the biochemistry of the novel protein in a variety of disease states, ranging from oncology to neurodegenerative disorders. Here, we present a scalable gram-level synthesis of the thiazolidinedione (TZD) containing NL-1 from the precursor CI-987 using the Hantzsch ester reduction as an alternative to conventional lithium borohydride or cobalt chloride-based methods. This optimized protocol enables the reliable production of NL-1 in quantities sufficient for preclinical disease modeling.

Nitriles to Amines: LiAlH4 Reduction
As shown below, the mechanism involves three steps. Firstly, the hydride ion acting as a nucleophile attacks the nitrile carbon to form an anion. In the second step, a second equivalent of the hydride ion attacks the anion to...

Amides to Amines: LiAlH4 Reduction
Amide reduction requires two equivalents of the reducing agent, acting as a source of hydride ions. As shown in the figure, the reaction is initiated with a nucleophilic attack by the hydride ion at the carbonyl carbon to form a tetrahedral intermediate.

Though catalytic hydrogenation can reduce nitrobenzenes, the reduction is nonselective in the presence of other functional groups. For instance, if nitrobenzene contains an aldehyde group,...
