  Enantioselective synthesis of (S)- and (R)-α-methylserines: application to the synthesis of (S)- and (R)-N-Boc-N,O-isopropylidene-α-methylserinals

  摘要：

  This report describes the synthesis of enantiomerically pure (S)- and (R)-alpha -methylserines on a multigram scale, starting from the Weinreb amide of 2-methyl-2-propenoic acid and using a stereodivergent synthetic route that involves a Sharpless asymmetric dihydroxylation reaction. As a synthetic application of these quaternary alpha -amino acids, they were used as starting materials in the synthesis of the well-known valuable homochiral (S)- and (R)-N-Boc-N,O-isopropylidene-alpha -methylserinal building blocks.

  largazole embodies a compelling combination of a relatively simple, yet unique cyclic depsipeptide structure with remarkable levels of selective cytotoxicity against cancer cell lines versus nontransformed cells. The unique structure of largazole inspired a strategically novel and aggressive approach towards its expedient total synthesis. This involved an initial dissection into an epoxy aldehyde and an unprotected

  Details of the evolution of strategies toward convergent assembly of the histone deacetylase inhibiting natural product largazole exploiting gamma,delta-unsaturated-alpha,beta-epoxy-aldehydes and a thiazole-thiazoline containing omega-amino-acid are described. The initial N-heterocyclic carbene mediated redox amidation exploying these two types of building blocks representing largazole's structural domains of distinct biosynthetic origin directly afforded the seco-acid of largazole. This was accomplished without any protecting groups resident upon either thioester bearing epoxy-aldehyde or the tetrapeptide. However, the ineffective production of largazole via the final macrolactonization led to an alternative intramolecular esterification/macrolactamization strategy employing the established two building blocks. This provided largazole along with its C2-epimer via an unexpected inversion of the alpha-stereocenter at the valine residue. The biological evaluation demonstrated that both largazole and 2-epi-largazole led to dose-dependent increases of acetylation of histone H3, indicating their potencies as class I histone deacetylase selective inhibitiors. Enhanced p21 expression was also induced by largazole and its C2 epimer. In addition, 2-epi-largazole displayed more potent activity than largazole in cell viability assays against PC-3 and LNCaP prostate cancer cell lines.
