N-Acylphosphatidylethanolamine phospholipase D (NAPE-PLD) is regarded as the main enzyme responsible for the biosynthesis of N-acylethanolamines (NAEs), a family of bioactive lipid mediators. Previously, we reported N-(cyclopropylmethyl)-6-((S)-3-hydroxypyrrolidin-1-yl)-2-((S)-3-phenylpiperidin-1-yl)pyrimidine-4-carboxamide (1, LEI-401) as the first potent and selective NAPE-PLD inhibitor that decreased NAEs in the brains of freely moving mice and modulated emotional behavior [ Mock et al. Nat Chem. Biol., 2020, 16, 667-675 ]. Here, we describe the structure-activity relationship (SAR) of a library of pyrimidine-4-carboxamides as inhibitors of NAPE-PLD that led to the identification of LEI-401. A high-throughput screening hit was modified at three different substituents to optimize its potency and lipophilicity. Conformational restriction of an N-methylphenethylamine group by replacement with an (S)-3-phenylpiperidine increased the inhibitory potency 3-fold. Exchange of a morpholine substituent for an (S)-3-hydroxypyrrolidine reduced the lipophilicity and further increased activity by 10-fold, affording LEI-401 as a nanomolar potent inhibitor with drug-like properties. LEI-401 is a suitable pharmacological tool compound to investigate NAPE-PLD function in vitro and in vivo.

A redox-neutral Fe-catalyzed intramolecular C—H amidation of N-benzoyloxyureas is described. This methodology employs a simple iron complex in situ generated from Fe(OTf)2 and bipyridine as the catalyst and N-benzoyloxyureas as the nitrene prec

A rapid construction of THIQs by a Pd(II)-catalyzed C(sp2)-H olefination of free primary and secondary 2-phenylethylamines with high step- and atom-economy was reported. Notably, no substituent was required at the α-position to the amino group of the 2-phenylethylamines. The substrate scope was broad, and the reaction could also be applied to generate THIQs from the biologically active molecules such as the drug molecule baclofen and phenylalanine ester.

An investigation of the intramolecular cyclopropanation reactions of α-diazo-β-ketonitriles is reported. These studies reveal that α-diazo-β-ketonitriles exhibit unique reactivity in their ability to undergo arene cyclopropanation reactions; other similar acceptor-acceptor- substituted diazo substrates instead produce mixtures of C-H insertion and dimerization products. α-Diazo-β-ketonitriles also undergo highly efficient intramolecular cyclopropanation of tri- and tetrasubstituted alkenes. In addition, the α-cyano-α-ketocyclopropane products are demonstrated to serve as substrates for SN2, SN2′, and aldehyde cycloaddition reactions.
Asymmetric transfer hydrogenation of 1-naphthyl ketones by an ansa-Ru(II) complex of a DPEN-SO2N(Me)-(CH2)2(η 6-p-tol) combined ligand

The first second-generation designer Ru(II) catalyst 1b featuring an enantiopure N,C-(N-ethylene-N-methyl-sulfamoyl)-tethered (DPEN- κ2N,N′)/η6-toluene hybrid ligand is introduced. Using an S/C = 1000 in HCO2H-Et3N 5:2 transfer hydrogenation medium, secondary 1-naphthyl alcohols are obtained in up to >99.9% ee under mild conditions. Mechanistic factors are discussed.

Substituted 7,12-methano-dibenzazocines and 8,13-methanodibenzazonines, e.g., 7,12-dihydro-6,13-dimethyl-7,12-methano-6H-dibenz [c,f] azocine, are prepared by cyclizing 3-benzylamino or 3-phenethylamino -2-alkyl-indan-1-ols and are useful as anti-inflammatory agents.
