Sterically hindered N-acyl, gem-disubstituted amino acids are easily prepared via the addition of organometallic reagents to N-carboxyanhydrides (NCA). The process tolerates a wide variety of functional groups and allows the synthesis of amide products not readily accessible by traditional acylation chemistry. The existence of an isocyanate intermediate was established by in situ IR spectroscopy.

Future efforts will undeniably focus on the diversification of the new catalytic transformations. These may comprise an expansion of the substrate scope from aromatic and heteroaromatic compounds to other hydrocarbons. Keep reading other articles of 583-47-1. Reference of 583-47-1

The present invention is a method for purifying an NCA, including the steps of: a) dissolving an NCA contaminated with impurities into a solvent which is a good solvent and is not a chlorinated solvent followed by stirring to precipitate an undissolved impurity to afford a suspension, b) adding an acidic filter aid having ability to trap a basic impurity to the obtained suspension followed by filtration and/or forming a fixed bed of the acidic filter aid having ability to trap a basic impurity followed by filtering the suspension to bring the suspension to be in contact with the acidic filter aid having ability to trap a basic impurity, and c) adding the obtained filtrate dropwise to a poor solvent for NCA to crystallize out the NCA in which the impurities are removed. This makes it possible to purify a low-purity NCA conveniently to afford a high-purity NCA.

Synthetic Route of 583-47-1, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 583-47-1, molcular formula is C10H9NO3, introducing its new discovery.

Polymerization of N-carboxy anhydrides (NCAs) is the primary process used to prepare polypeptides. The synthesis of various pure NCAs is key to the efficient synthesis of polypeptides. The only practical method that can be used to synthesize NCAs requires harsh acidic conditions that make acid-labile substrates unusable and results in an undesired ring opening of NCAs. Basic-to-acidic flash switching and subsequent flash dilution technology in a microflow reactor was used to demonstrate the synthesis of NCAs. It is both rapid (0.1 s) and mild (20 C) and includes substrates containing acid-labile functional groups. The basic-to-acidic flash switching enabled both an acceleration of the desired NCA formation and avoided the undesired ring opening of NCAs. The flash dilution precluded the undesired decomposition of acid-labile functional groups. The developed process allowed the synthesis of various NCAs which cannot be readily synthesized using conventional batch methods.

Synthetic Route of 583-47-1, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 583-47-1, 4-Benzyloxazolidine-2,5-dione, introducing its new discovery.

Solutions of DL-phenylalanine-NCA in eight different solvents were thermostated at 20C for 4 days (and in two cases at 60C) without addition of initiators. Spontaneous polymerizations were observed in dimethylformamide (DMF), in N-methylpyrrolidone (NMP), and in dimethyl sulfoxide (DMSO). In dimethyl sulfoxide also sarcosine-NCA, L-alanine-NCA, D,L-leucine-NCA, and DL-valine-NCA underwent spontaneous polymerizations. However, in N-methylpyrrolidone, only sarcosine-NCA and L-alanine-NCA polymerized. The products of all these solvent-induced polymerizations were identified by MALDI-TOF mass spectrometry as cyclic oligo- and polypeptides. This fact and the finding that only the most nucleophilic solvents induce spontaneous polymerizations indicate a zwitterionic polymerization mechanism.

The N1-H1 imino group of the five-membered ring of the title compound, C10H9NO3, forms intermolecular hydrogen bonds between O1 along the a axis and between O3 along the b axis. Thus, a two-dimensional hydrogen-bonding network forms a layer perpendicular to the c axis. The layer, which consists of one of two independent molecules, stacks alternately along the c axis and produces a sandwich structure.
