Direct Intramolecular Aminoboration of Allenes

Direct intramolecular aminoboration of sulfonamidoallenes was realized using BCl3 as a boron source. The reactions benefited from the interaction between BCl3 and sulfonamides and provided a variety of borylvinyl heterocycles in good isolated yields. When chiral substrates were involved in the reactions, high stereoselectivity was observed, as can be ascertained by single-crystal X-ray diffraction experiments. Derivatization of the thus-obtained borylvinyl compounds proceeded readily, and different functionalities could be obtained via oxidation, halogenation, and Suzuki coupling reactions.

INHIBITORS OF ADENYLATE-FORMING ENZYME MENE

Provided herein are compounds of Formula (I) and pharmaceutically acceptable salts or tautomers thereof which may inhibit adenylate-forming enzymes. Also provided are pharmaceutical compositions, kits, uses, and methods involving the inventive compounds for the treatment and/or prevention of an infectious disease (e.g., bacterial infection (e.g., tuberculosis, methicillin- resistant Staphylococcus aureus)).

Structure-Based Design, Synthesis, and Biological Evaluation of Non-Acyl Sulfamate Inhibitors of the Adenylate-Forming Enzyme MenE

N-Acyl sulfamoyladenosines (acyl-AMS) have been used extensively to inhibit adenylate-forming enzymes that are involved in a wide range of biological processes. These acyl-AMS inhibitors are nonhydrolyzable mimics of the cognate acyl adenylate intermediates that are bound tightly by adenylate-forming enzymes. However, the anionic acyl sulfamate moiety presents a pharmacological liability that may be detrimental to cell permeability and pharmacokinetic profiles. We have previously developed the acyl sulfamate OSB-AMS (1) as a potent inhibitor of the adenylate-forming enzyme MenE, an o-succinylbenzoate-CoA (OSB-CoA) synthetase that is required for bacterial menaquinone biosynthesis. Herein, we report the use of computational docking to develop novel, non-acyl sulfamate inhibitors of MenE. A m-phenyl ether-linked analogue (5) was found to be the most potent inhibitor (IC50 = 8 μM; Kd = 244 nM), and its X-ray co-crystal structure was determined to characterize its binding mode in comparison to the computational prediction. This work provides a framework for the development of potent non-acyl sulfamate inhibitors of other adenylate-forming enzymes in the future.

Flexible synthesis of anthracycline aglycone mimics via domino carbopalladation reactions

A synthesis of anthracycline aglycone derivatives is described. The key step utilizes a powerful domino carbopalladation approach and subsequent ring closure. During this process two of the four rings of the anthracycline scaffold are formed. Differently substituted carbohydrates and dialkyne chains serve as versatile and simple starting materials for the reaction sequence. Diverse building blocks lead to a variety of different products and a broad range of structural diversity.

Synthetic studies on the solanacol ABC ring system by cation-initiated cascade cyclization: Implications for strigolactone biosynthesis

We report a new method for constructing the ABC ring system of strigolactones, in a single step from a simple linear precursor by acid-catalyzed double cyclization. The reaction proceeds with a high degree of stereochemical control, which can be qualitatively rationalized using DFT calculations. Our concise synthetic approach offers a new model for thinking about the (as yet) unknown chemistry that is employed in the biosynthetic pathways leading to this class of plant hormones.
