hemin, divinylbenzene, and 2-methyl-5-vinylpyridine was synthesized by suspension copolymerization. Substitution reactions of primary, secondary, and tertiary alkylhalides with the hemin copolymer combined with cyanide, azide, and thiocyanate ions were given satisfactory yields. This reaction mechanism was revealed to be a SNi type on the basis of stereochemical study. The hemin copolymer was not only

Conversion of C-terminal carboxy groups of N-protected α-amino acids to the corresponding 3,5-dinitrobenzoyl mixed anhydrides, followed by treatment with α-azido esters and trialkylphosphines, affords good yields of peptides, without appreciable formation of epimers even for reactions involving Phe–Val and Val–Val couplings and/or N-benzoyl α-amino acids.
Preparation of (R)-2-azidoesters from 2-((p-nitrobenzene)sulfonyl)oxy esters and their use as protected amino acid equivalents for the synthesis of di- and tripeptides containing D-amino acid constituents

(R)-2-Azidoesters and their derived (R)-2-azido acids are readily prepared from common aminoacids by an inversion methodology that employs (S)-2-nosyloxyesters as key intermediates. The (R)-2- azidoesters can be used as protected aminoacid equivalents in peptide synthesis. Basic hydrolysis frees the carboxyl group. Triphenylphosphine/water is used to free the amine group. By these reactions a variety
One-Pot Synthesis of 1,4-Disubstituted 1,2,3-Triazoles from Aldehydes and Amines

DOI:10.1055/s-0029-1218267
日期:2009.11
A one-pot, three-step synthesis of 1,4-disubstituted1,2,3-triazoles from aldehyde and amine has been developed by in situ transformation of aldehyde into alkyne, followed by diazo- transfer of amine into azide and subsequent cycloaddition. This pro- cedure allowed the synthesis of fluorescent amino acid derivatives as well as glycoconjugate mimetics.

to look for concise and efficient methods for the synthesis of this unit. In this work, a new strategy was developed in which a one-pot synthesis of N-phosphorylated amides was achieved by a three-component reaction with carboxylic acids, phosphorus chlorides and azides under mild reaction conditions. To our knowledge, this is the first study in which this framework was constructed through a multicomponent
