, (2019/05/22)
Heterocyclic compounds of Formula (I) and pharmaceutically acceptable salt thereof are disclosed. The use of such heterocyclic compounds and pharmaceutically acceptable salt thereof for the treatment of cancers, and more particularly cancers sensitive to mitochondrial activity inhibition and increased reactive oxygen species (ROS) levels, is also disclosed. Such cancers include acute myeloid leukemia (AML), preferably AML characterized by certain features, such as high level of expression of one or more Homeobox (HOX)-network genes, high and/or low expression of specific genes, the presence of one or more cytogenetic or molecular risk factors such as intermediate cytogenetic risk, Normal Karyotype (A/K), mutated NPM1, mutated CEBPA, mutated FLT3, mutated DNMT3A, mutated TET2, mutated IDH1, mutated IDH2, mutated RUNX1, mutated WT1, mutated SRSF2, intermediate cytogenetic risk with abnormal karyotype (intern(abnK)), trisomy 8 (+8) and/or abnormal chromosome (5/7), and/or a high leukemic stem cell (LSC) frequency.

The reactive nature of carbenes can be modulated, and ultimately reversed, by receiving additional electron density from a metal. Here, it is shown that Au nanoparticles (NPs) generate an electron-rich carbene on surface after transferring electron density to the carbonyl group of an in situ activated diazoacetate, as assessed by Fourier transformed infrared (FT-IR) spectroscopy, magic angle spinning nuclear magnetic resonance (MAS NMR), and Raman spectroscopy. Density functional theory (DFT) calculations support the observed experimental values and unveil the participation of at least three different Au atoms during carbene stabilization. The surface stabilized carbene shows an extraordinary stability against nucleophiles and reacts with electrophiles to give new products. These findings showcase the ability of catalytic Au NPs to inject electron density in energetically high but symmetrically allowed valence orbitals of sluggish molecules.
Olefin cyclopropanation catalyzed by new diiminophosphorane and triiminophosphorane complexes of copper and palladium

Chelating diiminophosphorane and tripodal iminophosphorane copper and palladium complexes are found to efficiently catalyze the cyclopropanation of activated monosubstituted olefins with ethyl diazoacetate. Cycloolefins, and linear α-olefins are somewhat
Monomeric Rhodium(II) Catalysts for the Preparation of Aziridines and Enantioselective Formation of Cyclopropanes from Ethyl Diazoacetate at Room Temperature

, p. 9705 - 9710 (2007/10/03)
A family of bis(oxazoline) complexes of coordinatively unsaturated monomeric rhodium (II) (2a,b,3a,b) are described. These complexes serve as catalysts for cyclopropanation of olefins by ethyl diazoacetate, giving excellent yields (66-84%). The reaction shows an unusual preference for formation of the cis isomers. Catalytic aziridination of N-aryl imines with diazoacetate is also described.
Soluble Polymer-Supported Ruthenium Porphyrin Catalysts for Epoxidation, Cyclopropanation, and Aziridination of Alkenes

, p. 1911 - 1914 (2007/10/03)
(Matrix Presented) Attachment of poly(ethylene glycol) (PEG) to ruthenium porphyrin via a covalent etheric bond gives soluble polymer-supported ruthenium catalysts 3-5. These catalysts exhibit high reactivity and selectivity toward alkene epoxidation with 2,6-dichloropyridine N-oxide and alkene cyclopropanation with diazo compounds. The application of these catalysts in the synthesis of unstable organic compounds has been demonstrated.
