Ide, Takafumi published the artcileLate-Stage Intermolecular Allylic C-H Amination, SDS of cas: 598-50-5, the main research area is trichloroethoxy sulfamyl olefin preparation allylic amination regioselective chemoselective diastereoselective.

A sustainable manganese perchlorophthalocyanine catalyst [MnIII(ClPc)]2 achieved selective, preparative intermol. allylic C-H amination of 32 cyclic and linear compounds, including ones housing basic amines and competing sites for allylic, ethereal and benzylic amination were reported. Mechanistic studies supported that the high selectivity of [MnIII(ClPc)] may be attributed to its electrophilic, bulky nature and stepwise amination mechanism. Late-stage amination was demonstrated on five distinct classes of natural products generally with >20:1 site-, regio- and diastereoselectivity.

Ran, Xiaoyun published the artcileA novel route to unsymmetrical disubstituted ureas and thioureas by HMPA catalyzed reductive alkylation with trichlorosilane, Product Details of C2H6N2O, the main research area is unsym disubstituted urea preparation chemoselective; aldehyde monosubstituted urea reductive alkylation HMPA catalyst; ketone monosubstituted urea reductive alkylation HMPA catalyst; disubstituted thiourea unsym preparation chemoselective; monosubstituted thiourea aldehyde reductive alkylation HMPA catalyst; thiourea monosubstituted ketone reductive alkylation HMPA catalyst.

An hexamethylphosphoramide (HMPA) catalyzed reductive alkylation of ureas and thioureas with trichlorosilane under mild reaction conditions was developed. Both aldehydes and ketones could be used as efficient alkylation reagents in this method to obtain unsym. disubstituted ureas R1NHC(O)NHR2 [R1 = n-Pr, cyclohexyl, Bn, etc.; R2 = Me, Ph, PhC(O), etc.] and thioureas R3NHC(S)NHR4 [R3 = n-Pr, Bn, CH2CH=CHPh, etc.; R4 = Me, Ph, 4-MeOC6H4, 4-FC6H4] in moderate to high yields. A variety of di- and trisubstituted ureas and thioureas were easily prepared by this new reductive alkylation method. This protocol exhibited excellent functional group tolerance, chemoselectivity and practicality.

The present study deals with the self-assembly of a pure graft copolymer: Soluplus and a non-ionic surfactant: Solutol HS15 and focuses on their clouding behavior [expressed as cloud point (CP)] in the presence of different additives viz. inorganic salts (NaF, NaCl, NaBr, NaI, NaNO3, KCl, KBr, KI), bile salts (sodium cholate-NaC, sodium taurocholate-NaTC, sodium deoxycholate-NaDC), denaturants (urea, methylurea, dimethylurea), amino acids (alanine, glycine, lysine, valine, cysteine hydrochloride), sugars (glucose, fructose, mannitol, sucrose, maltose, lactose), cationic surfactants (cetyltrimethylammonium bromide-CTAB, tetradecyltrimethylammonium bromide-TTAB, dodecyltrimethylammonium bromide-DTAB) and alcs. (methanol, ethanol, propanol, 1-butanol, ethanediol, 1,3-propanediol, 1,4-butanediol). The aqueous solutions of these amphiphiles show a complex phase behavior and have revealed the occurrences of spherical micelles using dynamic light scattering (DLS) and small-angle neutron scattering (SANS) techniques. Herein, we report the variation of amphiphilic CP in the presence of different kinds of additives that show the influence of the water structure and its hydrophobicity, making this study important for pharmaceutical/biomedical applications.

Schuhmacher, Anne published the artcileCatalytic Synthesis of Potassium Acyltrifluoroborates (KATs) from Boronic Acids and the Thioimidate KAT Transfer Reagent, Product Details of C2H6N2O, the main research area is potassium acyltrifluoroborate preparation; boronic acid thioimidate transfer reagent cross coupling palladium catalyst; acylboron compounds; boronic acids; cross-coupling; synthetic methods; zwitterions.

We report the synthesis of potassium acyltrifluoroborates (KATs) by a palladium-catalyzed cross-coupling of boronic acids and the thioimidate KAT transfer reagent. The combination of widely available aryl- and vinylboronic acids with com. available thioimidate using catalytic PdII and a CuII additive enables the preparation of KATs in high yields and with good functional group tolerance. This formal insertion of CO into organoboronic acids can also be applied to boronic acid pinacol esters and potassium organotrifluoroborates using a slightly modified procedure. The cross-coupling can be telescoped into the one-pot synthesis of amides and α-aminotrifluoroborates by exploiting the unique chem. of KATs and their trifluoroborate iminium (TIM) derivatives

Pokluda, Adam published the artcileRobust Photocatalytic Method Using Ethylene-Bridged Flavinium Salts for the Aerobic Oxidation of Unactivated Benzylic Substrates, Formula: C2H6N2O, the main research area is ethylene bridged flavinium salt photoredox catalyst preparation fluorescence; benzyl ethylene bridged flavinium salt photocatalyst aerobic oxidation; aryl ketone preparation.

A series of ethylene-bridged flavinium salts I (R1, R2 = H, OMe, CF3, Cl; R1R2 = OCH2O; R3 = H, Me, n-octyl) has been synthesized and their photochem. and electrochem. properties have been studied. Out of these compounds, 7,8-dimethoxy-3-methyl-1,10-ethylenealloxazinium chloride I [R1 = R2 = MeO; R3 = Me; (II)] was found to be a superior photooxidation catalyst. The flavinium salt II proved to be robust enough for practical applications in benzylic oxidations/oxygenations, which was demonstrated using a series of substrates with high oxidation potential, i.e., 1-phenylethanol, ethylbenzene, diphenylmethane and diphenylmethanol derivatives substituted with electron-withdrawing groups (Cl or CF3). The unique capabilities of the compound II can be attributed to its high photostability and participation via a relatively long-lived singlet excited state, which was confirmed using spectroscopic studies, electrochem. measurements and TD-DFT calculations This allows the maximum use of the oxidation power of the compound II, which was given by its singlet excited state reduction potential of +2.4 V. This compound can be used as an alternative photocatalyst for even more difficult substrates.

Komar, Mario published the artcileApplication of Deep Eutectic Solvents in the Synthesis of Substituted 2-Mercaptoquinazolin-4(3H)-Ones: A Comparison of Selected Green Chemistry Methods, Application of 1-Methylurea, the main research area is mercaptoquinazolinone green preparation; anthranilic acid isothiocyanate microwave ultrasound choline chloride urea catalyst; 2-mercaptoquinazolin-4(3H)-one; deep eutectic solvents; green chemistry; microwave-assisted synthesis; ultrasound-assisted synthesis.

In this study, deep eutectic solvents (DESs) were used as green and eco-friendly media for the synthesis of substituted 2-mercaptoquinazolin-4(3H)-ones I [R1 = H, 6-I, 6-Br, 7-Cl, 6,8-dichloro; R2 = Me, Ph, Bn, etc.] from different anthranilic acids and aliphatic or aromatic isothiocyanates. A model reaction on anthranilic acid and Ph isothiocyanate was performed in 20 choline chloride-based DESs at 80 °C to find the best solvent. Based on the product yield, choline chloride:urea (1:2) DES was found to be the most effective, while DESs acted both as solvents and catalysts. Desired compounds were prepared with moderate to good yields using stirring, microwave-assisted, and ultrasound-assisted synthesis. Significantly higher yields were obtained with mixing and ultrasonication (16-76%), while microwave-induced synthesis showed lower effectiveness (13-49%). The structures of the synthesized compounds were confirmed by 1H and 13C NMR spectroscopy.
