Diaryl formation is achieved by coupling phenols and (hetero)aryl halides under the catalysis of CuI/N,N?-bis(2-phenylphenyl) oxalamide (BPPO) or CuI/N-(2-phenylphenyl)-N?-benzyl oxalamide (PPBO) at 90 C using DMF or MeCN as the solvent. Only 0.2-2 mol % CuI and ligand are required for complete conversion, which represents the lowest catalytic loadings for a general Cu/ligand-catalyzed diaryl ether formation.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 10075-51-1

Carbon?carbon bond cleavage/functionalization is synthetically valuable, and selective carbonyl?C(sp3) bond cleavage/alkynylation presents a new perspective in constructing ynamides, ynoates, and ynones. Reported here is the first alkoxyl-radical-enabled carbonyl?C(sp3) bond cleavage/alkynylation reaction by photoredox catalysis. The use of novel cyclic iodine(III) reagents are essential for beta-carbonyl alkoxyl radical generation from beta-carbonyl alcohols, including alcohols with high redox potential (EoxP >2.2 V vs. SCE in MeCN). beta-Amide, beta-ester, and beta-ketone alcohols yield ynamides, ynoates, and ynones, respectively, for the first time, with excellent regio- and chemoselectivity under mild reaction conditions.

The design and synthesis of a series of C28 amine-based betulinic acid derivatives as HIV-1 maturation inhibitors is described. This series represents a continuation of efforts following on from previous studies of C-3 benzoic acid-substituted betulinic acid derivatives as HIV-1 maturation inhibitors (MIs) that were explored in the context of C-28 amide substituents. Compared to the C-28 amide series, the C-28 amine derivatives exhibited further improvements in HIV-1 inhibitory activity toward polymorphisms in the Gag polyprotein as well as improved activity in the presence of human serum. However, plasma exposure of basic amines following oral administration to rats was generally low, leading to a focus on moderating the basicity of the amine moiety distal from the triterpene core. The thiomorpholine dioxide (TMD) 20 emerged from this study as a compound with the optimal antiviral activity and an acceptable pharmacokinetic profile in the C-28 amine series. Compared to the C-28 amide 3, 20 offers a 2- to 4-fold improvement in potency towards the screening viruses, exhibits low shifts in the EC50 values toward the V370A and DeltaV370 viruses in the presence of human serum or human serum albumin, and demonstrates improved potency towards the polymorphic T371A and V362I virus variants.

A protected pyruvate equivalent is described that allows arylation and arylation/alkylation reactions to be performed at the methyl group. Utilization of the OBO derivative of the pyruvate ester allowed the application of palladium catalyzed arylation reactions together with subsequent alkylation, under basic conditions. Moreover, the OBO protecting group could be easily removed in one step to provide access to a wide range of substituted pyruvate derivatives.

Mannich type reactions of a preformed aldimine with various carbonyl compounds were investigated with a series of functionalised indoline derivatives as catalysts: indoline-3-carboxylic acid, the diphenylcarbinol analogue and O-protected silyl ether analogues. All compounds were readily prepared in enantiopure form by using an enzymatic kinetic resolution as a key step (E?100). The alcohol and ether catalysts failed to induce complete chirality transfer but did afford the Mannich bases in good yields and high diastereomeric ratios, whereas the acid catalyst gave the products in a highly diastereo- and enantioselective manner. The absolute configuration of the products was determined by a syn-anti isomerisation protocol, initiated by the sterically demanding base 1,8-diazabicyclo[5.4.0]undec-7-ene. Enzymatic kinetic resolution (E?100) was applied in the synthesis of enantiopure indoline-3-carboxylic acid (1); the corresponding derivatives 2-4 were readily obtained after standard transformations. Compounds 1-4 were applied as organocatalysts in Mannich-type reactions (see scheme) to afford the products with high anti selectivity at low temperatures, in moderate to good yields Copyright

The indole nucleus is a privileged heterocyclic scaffold, which is present in several natural and synthetic compounds. New synthetic strategies to access functionalized indoles have therefore attracted the attention of both synthetic and medicinal chemists over the decades. In this study, the bismuth nitrate-promoted disproportionative condensation of indoles with cyclohexanone in one pot, to yield C3-cyclohexyl substituted indoles and 1,3-di(1H-indol-3-yl)benzene derivatives is reported for the first time. Using 3-methylindole with cyclopentanone, cyclohexanone, and cycloheptanone results in new and different synthetic pathways. The plausible reaction mechanisms are presented and supported with DFT (M06-2X/6-31+G(d,p)) calculations.

Catalytic asymmetric N-alkylation of indoles and carbazoles represents a family of important but underdeveloped reactions. Herein, we describe a new organocatalytic strategy in which in situ generated aza-para-quinone methides are employed as the alkylating reagent. With the proper choice of a chiral phosphoric acid and an N-protective group, the intermolecular C?N bond formation with various indole and carbazole nucleophiles proceeded efficiently under mild conditions with excellent enantioselectivity and functional-group compatibility. Control experiments and kinetic studies provided important insight into the reaction mechanism.
