Synthesis and Application of Glycopeptide and Glycoprotein Mimetics.

«Studies toward Total Synthesis of (+/-)-Caldaphnidine C via One-Pot Sequential Intramolecular Vilsmeier-Haack and Azomethine Ylide 1,3-Dipolar Cycloaddition» J.

A concise synthesis of fused bicyclic pyrrolidines via 1,3-dipolar cycloaddition of azomethine ylides is reported. The exo cycloadduct isomer enables the synthesis of a novel cyclic amidine toward the preparation of a potential human histamine H4 receptor antagonist. The minor endo isomer led to the isolation of a new triazine ring through an intramolecular reductive cyclisation

Living Radical Polymerization as a Tool for the Synthesis of Polymer-Protein/Peptide Bioconjugates.

H., His6 tag-assisted chemical protein synthesis.

N2 - An efficient, diastereoselective route to 2,5,6,7-tetrasubstituted 1H- pyrrolo[1,2-c]imidazoles has been developed using azomethine ylide cycloaddition and urea cyclization reactions. Relative stereochemical assignments at the four contiguous pyrrolidine stereogenic centers were established by single-crystal X-ray analysis.

AB - An efficient, diastereoselective route to 2,5,6,7-tetrasubstituted 1H- pyrrolo[1,2-c]imidazoles has been developed using azomethine ylide cycloaddition and urea cyclization reactions. Relative stereochemical assignments at the four contiguous pyrrolidine stereogenic centers were established by single-crystal X-ray analysis.

AB - An efficient, diastereoselective route to 2,5,6,7-tetrasubstituted-1H- pyrrolo[1,2-c]imidazoles has been developed using solid-phase intramolecular azomethine ylide cycloaddition and carbanilide cyclization chemistries. To successfully execute this eight-step protocol in the solid phase, it was necessary to insert a spacer moiety between the resin and glycinate functional group. Experiments addressing the stereoselectivity of the 1,3- dipolar cycloaddition step as well as the cyclative release step are also presented.
