Supramolecular nanocarrier of siRNA from PEG-based block catiomer carrying diamine side chain with distinctive pKa directed to enhance intracellular gene silencing

An siRNA nanocarrier formed through self-assembly of PEG-based block catiomer possessing two distinct amino groups with different pKa values in a side chain was developed. This design provided the carrier with a sufficient siRNA complexation and an assumed buffering capacity in the endosomes, allowing it to exhibit remarkable gene knockdown abilities as well as sufficient serum tolerability.

Recyclable 2nd generation ionic liquids as green solvents for the oxidation of alcohols with hypervalent iodine reagents

Alcohols undergo smooth oxidation with iodoxybenzoic acid (IBX) or with Dess-Martin-Periodinane (DMP) in hydrophilic [bmim]BF4 and hydrophobic [bmim]PF6 ionic liquids at room temperature under mild conditions to afford the corresponding carbonyl compounds in excellent yields with high selectivity. IBX and DMP promoted oxidations are faster in ionic liquids when compared to conventional solvents such as DMSO, DMF, EtOAc and H2O. The recovery of the byproduct iodosobenzoic acid (IBA) is especially simple in ionic liquids. The recovered ionic liquids can be recycled in subsequent reactions with consistent activity.

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 108149-65-1

Enantioselective synthesis of bridged bicyclic ring systems

(Chemical Equation Presented) The type 2 intramolecular Diels-Alder (IMDA) reaction is a valuable method for synthesis of both carbocyclic and heterocyclic bridged bicyclo[5.3.1]undecane and bicyclo[4.3.1]decane ring systems. These structures are common to a number of biologically important natural products. Asymmetric variants of the type 2 IMDA reaction incorporating oxazolidinone chiral auxiliaries have been evaluated. This study has resulted in systems that deliver bridged bicyclic [5.3.1] and [4.3.1] ring systems in high diastereomeric (97-99% de) and enantiomeric purity.

A reasonably stereospecific multistep conversion of Boc-protected alpha-amino acids to Phth-protected beta3-amino acids

A method for the synthesis of beta3-amino acids starting from alpha-amino acids is described. This conversion can be effected by an eight-step procedure which involves the transformation of the carboxylic group into an alkyne followed by a selenium-mediated conversion of the carbon-carbon triple bond to a Se-phenyl selenocarboxylate intermediate. The reactive Se-phenyl selenocarboxylate intermediates can be trapped with water, alcohols or the amine of an amino acid derivative to give beta3-amino acids, beta3-amino esters or mixed peptides, respectively. The whole transformations of the carboxylic group into an alkyne and of the alkyne group into beta3-amino acids may not require purification of the intermediate products but a work-up and isolation procedure of crude materials.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 139009-66-8, help many people in the next few years.Recommanded Product: (S)-N-Boc-2,2-dimethyloxazolidine-4-carboxylic Acid

Metallations and reactions with electrophiles of 4-isopropyl-5,5-diphenyloxazolidin-2-one (DIOZ) with N-allyl and N-propargyl substituents: Chiral homoenolate reagents

N-Allyl, N-cinnamyl, and N-(3-trimethylsilyl)propargyl derivatives of 4-isopropyl-5,5-diphenyloxazolidin-2-one (DIOZ) are prepared by lithiation of the parent DIOZ (with BuLi in THF) and reaction with the corresponding bromides (Scheme 1). Lithiation in the same solvent, with deprotonation by BuLi on the allylic or propargylic CH2 group at dry-ice temperature, provides colorful solutions, which are either combined with aldehydes or ketones directly or after addition (with or without warming) of (Me2N)3TiCl or (i-PrO)3TiCl. Conditions have thus been elaborated under which all three types of conjugated lithium compounds react in the gamma-position with respect to the oxazolidinone N-atom: carbamoyl derivatives of enamines and allenyl amines are formed in yields ranging from 60 to 80% and with diastereoselectivities up to 98% (Schemes 2-5). The C= C bond of the N-hydroxyalkenyl groups has (Z)-configuration (products 5 and 8), the allene chirality axis has (M)-configuration (products 9), and the addition to aldehydes and unsymmetrical ketones has taken place preferentially from the Si face. A mechanistic model is proposed that is compatible with the stereochemical outcome (assuming kinetic control and disregarding the presence of Li and Ti species in the reaction mixture; cf. L, M in Fig. 4). Hydrolysis of the enamine derivatives leads to lactols, oxidizable to gamma-lactones, with recovery of the crystalline oxazolidinone, as demonstrated in three cases (Scheme 6). Thus, the application of chiral oxazolidinone auxiliaries (cf. Figs. 1 and 2) has been extended to the overall enantioselective preparation of homoaldols.

Copper(II)-catalyzed amidations of alkynyl bromides as a general synthesis of ynamides and Z-enamides. An intramolecular amidation for the synthesis of macrocydic ynamides

A general and efficient method for the coupling of a wide range of amides with alkynyl bromides is described here. This novel amidation reaction involves a catalytic protocol using copper(II) sulfate-pentahydrate and 1,10-phenanthroline to direct the sp-C-N bond formation, leading to a structurally diverse array of ynamides including macrocyclic ynamides via an intramolecular amidation. Given the surging interest in ynamide chemistry, this atom economical synthesis of ynamides should invoke further attention from the synthetic organic community.
