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.

A route to 2-phenyl-4,5-dihydrooxazole-4-carbonitrile N-oxide 7 has been developed starting from (S)-serine methyl ester and involving dehydration of the 4-nitromethyl derivative 13 using m-tolylene diisocyanate and triethylamine.Cycloaddition of the nitrile oxide to styrene afforded a 55:45 mixture of diastereoisomeric dihydroisoxazoles 21 and 22; furazan N-oxides 19 and 20 were also formed in a competing dimerisation.The analogous (R)-oxazolidine-4-carbonitrile oxide 8, also prepared from (S)-serine methyl ester, reacted similarly with styrene, oct-1-ene and diethyl fumarate to afford ca. 1:1 mixtures of adducts.The structures of the dihydrooxazole-dihydroisoxazole adduct 21 and furazan N-oxide 20 were determined by X-ray crystallography.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.I hope my blog about 95715-86-9 is helpful to your research. name: Methyl (R)-N-Boc-2,2-dimethyloxazolidine-4-carboxylate

The four stereoisomers of sphingosine and sphinganine can be produced in protected form by a short, convergent, biomimetic synthesis from serine. Yields are good (26-38% overall from commercially available serine derivatives), and the stereoselectivities are excellent (>92% de, >95% ee). Several sphingosine L-threo-sphingosine analogues with modified, functionalized tails were prepared to demonstrate the versatility of the method.

Chemistry graduates have much scope to use their knowledge in a range of research sectors, including roles within chemical engineering, chemical and related industries, healthcare and more. Reference of 139009-66-8,

Total synthesis of duocarmycin SA (1), an extremely potent cytotoxic antibiotic, was achieved in the racemic form at first by effectively utilizing two reactions as key steps, (i) an intramolecular Heck reaction of the benzyl ether 21a, derived from a dihydropyridine 13a and a pyrrole derivative 11, to form tricyclic compounds 25a and 26a, and (ii) a modified Mitsunobu reaction on the diol derivative 40 for the construction of compound 41 having the pivotal pharmacophore of a cyclopropanoindolinone partial structure, which is critical for the high biological activities of 1. Next, optical resolution of an intermediary racemic secondary alcohol 50 was cleanly attained by derivatizing it to (R)-O-methylmandelates 52 and 53, and the resulting chiral alcohols (+)-50 and (-)-50 were respectively transformed into unnatural (-)-1 and natural (+)-1. Finally inversion of the secondary alcohol (+)-50 to the enantiomer (-)-50 was effected by using the Mitsunobu reaction. This constitutes an enantio-convergent total synthesis of natural duocarmycin SA (1) starting from a racemic compound.

Purpose: To achieve tunable pH-dependent drug release in tumor tissues. Methods: Poly(ethylene glycol)-poly(aspartic acid) [PEG-p(Asp)] containing 12 kDa PEG and pAsp (5, 15, and 35 repeating units) were prepared. Hydrazide linkers with spacers [glycine (Gly) and 4-aminobenzoate (Abz)] were introduced to PEG-p(Asp), followed by drug conjugation [doxorubicin (DOX)]. The block copolymer-drug conjugates were either reconstituted or dialyzed in aqueous solutions to prepare micelles. Drug release patterns were observed under sink conditions at pH 5.0 and 7.4, 37C, for 48 h. Results: A collection of six block copolymers with different chain lengths and spacers was synthesized. Drug binding yields were 13-43.6%. The polymer-drug conjugates formed <50 nm polymer micelles irrespective of polymer compositions. Gly-introduced polymer micelles showed marginal change in particle size (40±10 nm), while the size of Abz-micelles increased gradually from 10 to 40 nm as the polymer chain lengths increased. Drug release patterns of both Gly and Abz micelles were pH-dependent and tunable. The spacers appear to play a crucial role in controlling drug release and stability of polymer micelles in combination with block copolymer chain lengths. Conclusion: A drug delivery platform for tunable drug release was successfully developed with polymer micelles possessing spacer-modified hydrazone drug-binding linkers. A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction.
