Organocatalytic Enantioselective Vinylcyclopropane-Cyclopentene (VCP-CP) Rearrangement
(Wiley, 2023-05)
We have demonstrated that the catalytic and enantioselective vinylcyclopropane-cyclopentene rearrangement can be carried out on (vinylcyclopropyl)acetaldehydes through activation via enamine intermediates. The reaction ...
Asymmetric Dual Enamine Catalysis/Hydrogen Bonding Activation
(MDPI, 2023-07-11)
Asymmetric enamine base activation of carbonyl compounds is a well-known and widely used strategy for providing functionalization of organic compounds in an efficient way. The use of solely organic substances, which in ...
Desymmetrization of Oxabenzonorbornadienes through Brønsted Acid-Catalyzed Enantioselective (3+2) Cycloaddition with Hydrazones
(Wiley, 2023-07)
This work presents the desymmetrization of oxabenzonorbornadienes through the (3+2) cycloaddition reaction with hydrazones using a chiral Brønsted acid such as a BINOL-derived phosphoramide. This chiral acid catalyst appears ...
Consecutive Single-Crystal-to-Single-Crystal Isomerization of Novel Octamolybdate Anions within a Microporous Hybrid Framework with Robust Water Sorption Properties
(Wiley, 2023-10)
The 3D hybrid framework [{Cu(cyclam)}3(κ-Mo8O27)] ⋅ 14H2O (1) (cyclam=1,4,8,11-tetraazacyclotetradecane) undergoes sequential single-crystal-to-single-crystal transformations upon heating to afford two different anhydrous ...
H(N3)dap (Hdap = 2,6-Diaminopurine) Recognition by Cu2(EGTA): Structure, Physical Properties, and Density Functional Theory Calculations of [Cu4(μ-EGTA)2(μ-H(N3)dap)2(H2O)2]·7H2O
(MDPI, 2023-08-26)
Reactions in water between the Cu2(µ-EGTA) chelate (EGTA = ethylene-bis(oxyethyleneimino)tetraacetate(4-) ion) and Hdap in molar ratios 1:1 and 1:2 yield only blue crystals of the ternary compound [Cu4(μ-EGTA)2(μ-H(N3)da ...
The role of sample preparation in suspect and non-target screening for exposome analysis using human urine
(Elsevier, 2023-10)
The use of suspect and non-target screening (SNTS) for the characterization of the chemical exposome employing human biofluids is gaining attention. Among the biofluids, urine is one of the preferred matrices since organic ...
Directed C- H Allylation of Aromatic Carboxamides with Allyl Aryl Ethers under Cp*Co(III)-Catalysis
(Wiley-VCH, 2023-11-20)
The Cp*Co(III) C−H allylation of (hetero)arenes with allyl aryl ethers has been developed using an amide as directing group (24 examples). DFT calculations have shed light on the mechanistic course and reactivity pattern, ...
Thermochemical CO2 reduction catalyzed by homometallic and heterometallic nanoparticles generated from the thermolysis o supramolecularly assembled porous metal-adenine precursors
(American Chemical Society, 2023-10-09)
A family of unprecedented supramolecularly assembled porous metal–organic compounds (SMOFs), based on [Cu6M(μ-adeninato)6(μ3-OH)6(μ-H2O)6]2+ cations (MII: Cu, Co, Ni, and Zn) and different dicarboxylate anions (fumarate, ...
Copper(II)-porphyrin functionalized titanium(IV) metal-organic aerogels for the visible-light driven conversion of CO2 to alcohols
(Elsevier, 2023-08)
This manuscript covers the synthesis and characterization of a series of titanium based metal-organic aerogels (MOAs) functionalized with copper(II)-metalated porphyrins for their application in visible-light-driven carbon ...
