The coupling of acyl electrophiles with organometallic reagents represents a convergent route toward complex and versatile ketone products. Despite the mild conditions and high functional group tolerance, the cross-coupling of carboxylic acid derivatives, such as thioesters, and secondary organometallic reagents is an underdeveloped transformation. Herein, we disclose a convenient and efficient protocol for the Pd-catalyzed Fukuyama cross-coupling of secondary organozinc reagents with thioester electrophiles. Under these mild conditions, a range of thioesters possessing sensitive functional groups can be coupled with either activated or unactivated secondary organozinc halides in good yields. This method was expanded to include an acid chloride substrate, generating an aryl alkyl ketone in high yield. In addition, a modest dynamic kinetic resolution of the organozinc reagent can be achieved using chiral phosphoramidite ligands to furnish enantioenriched ketone products.

We’ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 52409-22-0, and how the biochemistry of the body works.Electric Literature of 52409-22-0

This paper describes the haloboration reaction of 1-alkynes and its application to organic synthesis. B-Bromo- or B-iodo-9-borabicyclo left bracket 3. 3. 1 right bracket -nonane (B-X-9-BBN) and other haloboranes react readily with 1-alkynes through Markovnikov cis-addition of the X-B moiety to C EQUVLNT C bonds. The haloboration occurs chemoselectively at terminal C EQUVLNT C bonds, but not at internal C EQUVLNT C, terminal and internal C equals C bonds. The haloboration adducts (I) thus obtained are valuable intermediates to afford various organic compounds stereospecifically in good yields, some of which are shown.

The activated alkynes have been used successfully for the first time as the dipolarophile in the palladium-catalyzed asymmetric (3 + 2) cycloaddition, affording highly functionalized cyclopentenes in good to high yields with high chemoselectivities and good to high enantioselectivities. The introduction of an additional carbonyl group at the alpha-position of the alkynyl esters is the key to activating the carbon-carbon triple bond. The reaction process was investigated, and an inverse process of Pd-catalyzed (3 + 2) cycloaddition was observed.

Amino-substituted biphenyls were obtained by Suzuki cross-coupling of 2,6-dibromoaniline with a phenylboronic acid (substituted with Me, NO 2, OH, OMe or Cl) preferably assisted by microwave irradiation. Conversion of the amino group into a thiol preceded a base-induced intramolecular substitution, also facilitated by microwave heating, to generate the second C-S bond of the target dibenzothiophene. The 1-, 2-, 3- or 4-substituted 6-halodibenzothiophenes obtained were subjected to a palladium-mediated coupling with 2-morpholin-4-yl-8-(4,4,5,5-tetramethyl-1,3,2- dioxaborolan-2-yl)-4H-chromen-4-one to give the respective 6-, 7-, 8- or 9-substituted dibenzothiophen-4-ylchromenones. These compounds were evaluated as inhibitors of DNA-dependent protein kinase (DNA-PK) and compared to the parent 8-(dibenzo[b,d]thiophen-4-yl)-2-morpholin-4-yl-4H-chromen-4-one. Notably, derivatives bearing hydroxy or methoxy substituents at C-8 or C-9 retained activity, whereas substitution at C-7 lowered activity. Substitution with chloro at C-6 was not detrimental to activity, but a chloro group at C-7 or C-8 reduced potency. The data indicate permissive elaboration of hydroxyl at C-8 or C-9, enabling the possibility of improved pharmaceutical properties, whilst retaining potency against DNA-PK.

Many neurodegenerative disorders are induced by protein conformational change. Prion diseases are characterized by protein conformational conversion from a normal cellular form (PrPC) to an abnormal scrapie isoform (PrPSc). PrP106-126 is an accepted model for studying the characteristics of PrPSc because they share many biological and physiochemical properties. To understand how metal complexes affect the property of the prion peptide, the present work investigated interactions between Pd complexes and PrP106-126 based on our previous research using Pt and Au complexes to target the peptide. The selected compounds (Pd(phen)Cl2, Pd(bipy)Cl2, and Pd(en)Cl2) showed strong binding affinity to PrP106-126 and affected the conformation and aggregation of this active peptide in a different binding mode. Our results indicate that it may be the metal ligand-induced spatial effect rather the binding affinity that contributes to better inhibition on peptide aggregation. This finding would prove valuable in helping design and develop novel metallodrugs against prion diseases.
