Cobalt-Catalyzed C(sp2)-H Carbonylation of Amino Acids Using Picolinamide as a Traceless Directing Group

Herein we report an efficient protocol for the C(sp2)-H carbonylation of amino acid derivatives based on an inexpensive cobalt(II) salt catalyst. Carbonylation was accomplished using picolinamide as a traceless directing group, CO (1 atm) as the carbonyl

Synthesis of small cyclic peptides via intramolecular Heck reactions

Tripeptides having a 3-bromobenzyl group at the C-termini and an acryloyl group at the N termini undergo efficient intramolecular Heck reactions to afford the corresponding cyclic peptides in good yields. Synthesis of two such peptides is discussed.

Correlation between the Configurational Structure and the Asymmetric Hydrogenation of Δ1-, Δ2-, and Δ3-Dehydrotripeptides

The heterogeneous catalytic hydrogenation of Δ1-dehydrotripeptides (Δ1-DHP), which have a β-turn structure, was carried out to give the corresponding tripeptides indicative of the very large diastereomeric excess, comparing with thos
