Synergistic Anti-Candida Activity of Bengazole A in the Presence of Bengamide A †. [PDF]

open access: yes, 2019
Bengazoles A⁻G from the marine sponge Jaspis sp. exhibit potent in vitro antifungal activity against Candida spp. and other pathogenic fungi. The mechanism of action (MOA) of bengazole A was explored in Candida albicans under both liquid culture and ...

Lewis‐Acidic Properties and Catalytic Behavior of Hydroboration‐ and Diolysis‐Derived NHC‐Stabilized Borenium Cations

open access: yesChemistry – A European Journal, EarlyView.
A series of thirteen (N‐heterocyclic carbene) NHC‐stabilized borenium cations is synthesized from NHC→BH3 complexes via hydroboration and condensation with diols. The novel compounds are fully characterized. Eight crystal structures are presented. Kinetic and NMR data show how the structural features translate to catalytic activity in hydrosilylation ...

Synthetic Routes to Coumarin(Benzopyrone)-Fused Five-Membered Aromatic Heterocycles Built on the α-Pyrone Moiety. Part II: Five-Membered Aromatic Rings with Multi Heteroatoms

open access: yesMolecules, 2021
Coumarins are natural heterocycles that widely contribute to the design of various biologically active compounds. Fusing different aromatic heterocycles with coumarin at its 3,4-position is one of the interesting approaches to generating novel molecules ...

Push–Pull Ynamines and Push–Pull Ynamides: Synthesis, Structure, Reactivity, and Application

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Push–pull ynamines and push–pull ynamides, which carry an EWG and an amino or amido group as EDG, are highly interesting classes of EDG‐EWG alkynes that have been intensively studied due to their exceptional reactivity. In this review, the synthesis, structure, reactivity, and application of push–pull ynamines, push–pull ynecarbamates, push–pull ...

A survey of liquid crystalline oxadiazoles

open access: yes, 2008
We propose a survey of those oxadiazole compounds, which are mesogenic. We will see that they can have bend-shaped molecules, a biaxial nematic phase, or other interesting peculiarities in the nematic and smectic phase.

Nickel‐Catalyzed Three‐Component Coupling Reactions of Iodobenzenes, an Isocyanide, and a Disilathiane: Access to Cyclic Thioimidates and Secondary Thioamides

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
The one‐pot synthesis of 3‐benzylidenbenzo[c]thiophen‐1‐amines was achieved through the nickel‐catalyzed three‐component coupling reaction of 1‐ethynyl‐2‐iodobenzenes, tert‐butyl isocyanide, and hexamethyldisilathiane. This procedure is applicable to the preparation of secondary thioamides using aryl iodides.
