Syntheses of 1,1-dimethylethyl (S)-4-formyl-2,2-dimethyl-3-oxazolidinecarboxylate (5) and 1,1-dimethylethyl (4S-trans)-4-formyl-2,2,5-trimethyl-3-oxazolidinecarboxylate (6) from commercially available serine and threonine derivatives are described.The method involves selective reduction of the corresponding oxazolidine esters 3 and 4 using diisobutylaluminum hydride at low temperature.These differentially protected beta-hydroxy-alpha-amino aldehydes are also shown to be produced in 93-95 percent enantiomeric excess (via NMR and HPLC analysis of the Mosher esterderivatives 8 and epi-8)-thus making them useful as chiral, nonracemic synthons for asymmetric synthesis.

Expeditious synthesis of enantiopure, orthogonally protected bis-alpha-amino acids (OPBAAs) and their use in a study of Nod1 stimulation

A convenient approach towards the synthesis of orthogonally protected chiral bis-a-amino acids (OPBAAs) is described. The key transformations include: (1) a highly stereoselective conjugation (alkylation) of the Schoellkopf bislactim ethers and oxazolidinyl alkyl halides to build a backbone skeleton; and (2) our orthogonal protection strategy. A series of enantiopure OPBAAs bearing a variety of alkyl chain as a spacer; two stereogenic centers; and three protecting groups were prepared as examples. These versatile molecules were applied to the synthesis of biologically interesting di- or tri-peptide analogues, including chiral iE-meso-DAP and A-iE-meso-DAP, for the study of Nod1 activation in the innate immune response.

Stereoselective Conjugate Addition of Organoaluminum Chlorides to alpha,beta-Unsaturated Carboxylic Acid Derivatives

Organoaluminum chlorides react smoothly with alpha,beta-unsaturated N-acyloxazolidinones providing chiral beta-branched carboxylic acid derivatives.An unexpected contrast between the mode of reaction of dimethylaluminum chloride and that of the higher homologues is observed.While diethylaluminum chloride and its higher homologues react with the acceptors at low temperature via a polar pathway, dimethylaluminum chloride requires activation by UV-light or radical initiation under otherwise identical conditions.With bicyclic oxazolidinones derived from galactosamine a high stereoselection is accomplished in the formation of the branched carboxylic acid derivative.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 145589-03-3 is helpful to your research. Electric Literature of 145589-03-3

Practical Cleavage of Acetals by Using an Odorless Thiol Immobilized on Silica

A practical, efficient and general method was developed for the deprotection of a variety of aromatic and aliphatic acetals to their corresponding catechol or diol derivatives using thiol immobilized on silica gel. This is an application for the well-known commercial solid-supported thiol (SiliaMetS Thiol). The procedure is mild and amenable to scale-up. It does not require inert atmosphere and clean conversions were observed. This method is applicable to substituted 1,3-benzodioxole and aliphatic acetals with different functionalities. It offers the advantage of a general route with high yield, which can be undertaken at ambient temperature.

A new methodology for the synthesis of beta-amino acids

A differentially functionalized succinic acid unit 6 undergoes alkylation with excellent regio- and high stereocontrol at the carbon alpha to the imide to furnish the alkylated product 7 in 60-83% yield. Selective removal of the imide provides 8 in 80-90% yields. Curtius rearrangement of 8 with retention of stereochemistry provides N-protected beta-amino acids (9) in 70-83% yields. Alternatively, selective deprotection of the ester group followed by Curtius rearrangement provides isomeric beta-amino acids 14a, 14b, and 14e in good yields. The methodology has been successfully applied to the synthesis of N-Boc-iturinic acid and 2-methyl-3-aminopropanoic acid, components of the antifungal peptide iturin and the cytotoxic depsipeptide cryptophycin respectively.
