beta-diketones: Important intermediates for drug synthesis

beta-diketones or 1,3-diketones are important intermediates not only as a key building blocks for the synthesis of core heterocycles such as pyrazole, isoxazole, and triazole in medicinal chemistry, but also as an invaluable chelating ligand for various lanthanide and transition metals in material chemistry. Apart from the process for the preparation of aromatic beta-diketones by the reaction of an acetophenone and a molar excess of an alphatic ester or an ester of benzoic acid in the presence of sodium alkoxide condensation agent (Claisen condensation) in an aromatic hydrocarbon solvent, various other methods have also been reported by the researchers which are least known and practiced. This review presents an extract of different procedures for synthesis of 1, 3-Diketones described by various authors along with the synthesis of 1, 4-diketones as well as novel beta-triketones which may help a researcher to find new possibilities in the related area.

SOLVENT DEPENDENT DIFFERENCE IN pKHB(1+) BEHAVIOUR IN N-METHYLANILINE AND N-PHENYLHYDROXYLAMINE

The pKBH(1+) values of the conjugate acids of N-phenylhydroxylamines change drastically when the pKBH(1+) values are determined in dimethyl sulfoxide (DMSO) rather than methanol.The Hammett rho values change from -5.69 to -1.20 on going from methanol to DMSO for protonated N-phenylhydroxylamines, in contrast to a shift of -4.70 to -4.83 for protonated N-methylanilines in the same two solvents.This large change in susceptibility indicates that the species from which the proton departs is not the same for protonated N-phenylhydroxylamines in the two solvents.Experimental and computational evidence supports ionization of the H(1+) from the O atom for the protonated N-phenylhydroxylamines in DMSO.

Promising Tools in Prostate Cancer Research: Selective Non-Steroidal Cytochrome P450 17A1 Inhibitors

Cytochrome P450 17A1 (CYP17A1) is an important target in the treatment of prostate cancer because it produces androgens required for tumour growth. The FDA has approved only one CYP17A1 inhibitor, abiraterone, which contains a steroidal scaffold similar to the endogenous CYP17A1 substrates. Abiraterone is structurally similar to the substrates of other cytochrome P450 enzymes involved in steroidogenesis, and interference can pose a liability in terms of side effects. Using non-steroidal scaffolds is expected to enable the design of compounds that interact more selectively with CYP17A1. Therefore, we combined a structure-based virtual screening approach with density functional theory (DFT) calculations to suggest non-steroidal compounds selective for CYP17A1. In vitro assays demonstrated that two such compounds selectively inhibited CYP17A1 17alpha-hydroxylase and 17,20-lyase activities with IC50 values in the nanomolar range, without affinity for the major drug-metabolizing CYP2D6 and CYP3A4 enzymes and CYP21A2, with the latter result confirmed in human H295R cells.

Synthesis and structure?activity relationship study of pyrazolo[3,4-d]pyrimidines as tyrosine kinase RET inhibitors

Three series of pyrazolo[3,4-d]pyrimidine derivatives were synthesized and evaluated as RET kinase inhibitors. Compounds 23a and 23c were identified to show significant activity both in the biochemical and the BaF3/CCDC6-RET cell assays. Compound 23c was found to significantly inhibit RET phosphorylation and down-stream signaling in BaF3/CCDC6-RET cells, confirming its potent cellular RET-targeting profile. Different from other RET inhibitors with equal potency against KDR that associated with severe toxicity, 23c did not show significant KDR-inhibition even at the concentration of 1?muM. These results demonstrated that 23c is a potent and selective RET inhibitor.

Direct Copper-Catalyzed Three-Component Synthesis of Sulfonamides

First introduced into medicines in the 1930s, the sulfonamide functional group continues to be present in a wide range of contemporary pharmaceuticals and agrochemicals. Despite their popularity in the design of modern bioactive molecules, the underpinning methods for sulfonamide synthesis are essentially unchanged since their introduction, and rely on the use of starting materials with preinstalled sulfur-functionality. Herein we report a direct single-step synthesis of sulfonamides that combines two of the largest monomer sets available in discovery chemistry, (hetero)aryl boronic acids and amines, along with sulfur dioxide, using a Cu(II) catalyst, to deliver a broad range of sulfonamides. Sulfur dioxide is provided by the surrogate reagent DABSO. The reaction tolerates broad variation in both coupling partners, including aryl, heteroaryl and alkenyl boronic acids, as well as cyclic and acyclic alkyl secondary amines, and primary anilines. We validate the method by showing that a variety of drugs, and drug-fragments, can be incorporated into the process.

Rhodium-catalyzed dynamic kinetic asymmetric transformations of racemic tertiary allylic trichloroacetimidates with anilines

The rhodium-catalyzed regio- and enantioselective amination of racemic tertiary allylic trichloroacetimidates with a variety of aniline nucleophiles is a direct and efficient route to chiral alpha,alpha-disubstituted allylic N-arylamines. We describe the first dynamic kinetic asymmetric transformations of racemic tertiary allylic electrophiles with anilines utilizing a chiral diene-ligated rhodium catalyst. The method allows for the formation of alpha,alpha-disubstituted allylic N-arylamines in moderate to good yields with good to excellent levels of regio- and enantioselectivity.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 5-(4-Hydroxyphenyl)isoxazole-3-carboxylic acid, you can also check out more blogs about33282-15-4

Access to Chiral 2,5-Pyrrolidinyl Dispirooxindoles via Dinuclear Zinc-Catalyzed Asymmetric Cascade Reactions

A series of new nonsymmetric semi-azacrown ether ligands were developed and applied to the asymmetric Michael/cyclic keto-imine formation/Friedel-Crafts alkylation reactions of 3-amino oxindole hydrochlorides and beta,gamma-unsaturated alpha-keto amides. A diversity of 2,5-pyrrolidinyl dispirooxindoles containing two nonadjacent spiro-quaternary stereocenters were obtained in excellent diastereoselectivities and moderate to excellent enantioselectivities (up to 95% ee). A possible catalytic cycle was proposed to explain the origin of the asymmetric induction.
