  Building constrained peptidomimetics: a convenient approach to 3-phenyl-5-vinyl substituted proline derivatives

  摘要：

  An approach to the synthesis of 3-phenyl-5-vinyl substituted prolines starting from readily available 2,3-disubstituted pentenoic acid derivatives is reported. The route converts the pentenoic acid derived starting materials into cyclic N-acyliminium ion precursors with the use of a hydroboration-Swern oxidation sequence. This overall transformation worked best when the initial alkylborane product was treated sequentially with excess MCPBA and then acetone prior to the Swern oxidation. In this way, a 70% yield of the desired N-acyliminium ion precursor could be obtained. Once in hand, the cyclic N-acyliminium ion precursor was used to make the desired 3-phenyl-5-vinyl substituted prolines. (C) 2001 Elsevier Science Ltd. All rights reserved.

  Terminal γ,δ-unsaturated amino acids, easily available by Claisen rearrangement or palladium-catalysed allylic alkylation, are excellent substrates for radical thiol additions. These click reactions allow the introduction of highly functionalized side-chains into a given amino acid or peptide. This protocol is suitable for the modification of all kinds of terminal alkenes, such as allyl protecting

  also observed. In all cases, excellent diastereo- and enantioselectivity of the branched alkylated product are observed. This new asymmetric reaction provides ready access to unusual quarternary amino acids, important building blocks for biological applications. The reactions complements the Pd AAA wherein the cinnamyl substrate leads to only the product of attack at the primary terminus of the allyl
