Design and synthesis of Fmoc-SPPS-ready iodoarene amino acid pre-catalysts and their reactivity in the catalytic oxytosylation of ketones

A small suite of iodo-aryl amide containing amino acids were synthesized and assessed as catalysts for the hypervalent iodine(III) mediated α-oxytosylation of ketones. The efficiency of each catalyst was determined by comparing the relative rates of catalysis in the direct α-oxytosylation of propiophenone. In addition, these catalysts can be easily converted to congeners that are suitable for Fmoc-solid phase peptide synthesis for facile incorporation into a chiral peptide framework. This work facilitates the broader goal of our program to develop peptide-based enantioselective catalysts for hypervalent iodine chemistry.

Prenyl carbamates: Preparation and deprotection

Prenyloxycarbonylimidazole (PreocIm) and prenyl p-nitrophenyl carbonate (PreocOC6H4p-NO2), two substitutes for the unstable prenyl chloroformate, allowed an efficient introduction of the prenyloxycarbonyl group to a variety of primary and secondary amines. Deprotection of prenyl carbamates was readily achieved by, first their conversion to 2-iodo-3-methoxy-3-methylbutyl carbamates with iodine in methanol followed by reductive β-elimination with zinc powder. These reaction conditions are compatible with the presence of a number of functional groups such as Boc and Cbz carbamates, sulfides, double bonds, indoles and aromatic ethers.

One-pot selective cleavage of prenyl carbamates using iodine in methanol followed by zinc

The prenyloxycarbonyl (Preoc) moiety was efficiently removed from carbamates to provde the corresponding amines in good to excellent yields (63-88 percent) by using iodine in methanol followed by treatment of the resulting β-methoxyiodides by zinc powder. The reaction conditions are compatible with the presence of a number of functional groups such as Boc and Cbz carbamates, sulfides, double bonds, indoles and aromatic methyl ethers.

127. C-glycoside analogues of N4-(2-Acetamido-2-deoxy-β-D-glucopyranosyl)-L-asparagine: synthesis and conformational analysis of a cyclic C-glycopeptide

The synthesis of C-glycosidic analogues 15-22 of N4-(2-acetamido-2-deoxy-β-D-glucopyranosyl)-L-asparagine (ASn(N4GlcNAc)) possessing a reversed amide bond as an isosteric replacement of the N-glycosidic linkage is presented. The peptide cyclo(-D-Pro-Phe-Ala-CGaa-Phe-Phe-) (CGaa = C-glycosylated amino acid; 24) was prepared to demonstrate that 3-[(3-acetamido-2,6-anhydro-4,5,7-tri-O-benzyl-3-deoxy-β-D-glycero-D- guloheptonoyl)amino]-2-[(9H-fluoren-9-yloxycarbonyl)amino]propanoic acid (22) can be used in solid-phase peptide synthesis. The conformation of 24 was determined by NMR and molecular-dynamics (MD) techniques. Evidence is provided that the CGaa side chain interacts with the peptide backbone. The different C-glycosylated amino acids 15-21 were prepared by coupling 3-acetamido-2,6-anhydro-4,5,7-tri-O-benzyl-3-deoxy-β-D-glycero-D-gulo- heptonic acid (4) with diamino-acid derivatives 8-14 in 83-96% yield. The synthesis of 4 was performed from 2-(acetamido-3,4,6-tri-O-benzyl-2-deoxy-β-D-glucopyranosyl)tributylstannane (2) by treatment with BuLi and CO2 in 83% yield. Similarly, propyl isocyanat yielded the glycoheptonamide 7 in 52% from 2. Compound 2 was obtained from 2-acetamido-3,4,6-tri-O-benzyl-2-deoxy-D-glucopyranose (1) by chlorination and addition of tributyltinlithium in 74% yield. A procedure for a multigram-scale synthesis of 1 is given.
