Abstract:

Boronic acids are prospective compounds in inhibition of metallo-β-lactamases as they form covalent adducts with the catalytic hydroxide anion in the enzymatic active site upon binding. We compare this chemical reaction in the active site of the New Delhi metallo-β-lactamase (NDM-1) with the hydrolysis of the antibacterial drug imipenem. The nucleophilic attack occurs with the energy barrier of 14 kcal/mol for imipenem and simultaneously upon binding a boronic acid inhibitor. A boron atom of an inhibitor exhibits stronger electrophilic properties than the carbonyl carbon atom of imipenem in a

The scaffold of benzo[b]thiophene 1,1-dioxides can be easily constructed through a copper(i)-catalyzed insertion of sulfur dioxide into (2-alkynylaryl)boronic acids. The reaction proceeds via insertion of sulfur dioxide and subsequent intramolecular 5-endo cyclization.

The structure of the title compound, C7H6BNO3, a new boron heterocycle, prepared by the condensation of (2-ethoxycarbonylphenyl)boronic acid and hydroxylamine, reveals the specific mode of intramolecular condensation between a phenylboronic acid and anorthohydroxamic acid substituent. The crystal structure shows that dehydration occurs to form a planar oxazaborinine ring possessing both phenol-like B—O—H and lactam functional groups. In the extended structure, intermolecular hydrogen bonding generates a 14-membered ring. To our knowledge, this is the first crystal structure determination invol

A non classical rearrangement is observed when thiopheno[c] and [b]bishomotropones react with ethanedithiol, leading to a naphtho[1,8-bc]thiophene and (or) a benzo[b]thiophene. The structure of the products is supported by deuterium labelling, 1H nmr spectra, and X-ray analysis of 5,6-diphenyl naphtho[1,8-bc]thiophene. A mechanism is proposed which implies an electronic transfer between a "soft" nucleophile and a "hard" acid, in the key step.

Abstract:

Abstract Multifunctional pyrazole derivative, i.e. 3-amino-1-(5-hydroxy-3-methyl-1H-pyrazol-4-yl)-1H-benzo[f]chromene-2-carbonitrile (PBCC) has been synthesized and characterized. To shed light on various properties of interests, the ground state geometry was optimized by adopting Density Functional Theory (PBE/TZ2P). The effect of different functionals on the absorption wavelengths was studied by using Time-Domain DFT (TDDFT), e.g. GGA functional PBE, hybrid functionals B3LYP and PBE0, rang separated functionals CAM-B3LYP, LCY-PBE and CAMY-B3LYP, Dispersion Corrections PBE-D3 and B3LYP-D3.
