• Evaluating β-amino acids as enantioselective organocatalysts of the Hajos–Parrish–Eder–Sauer–Wiechert reaction

  A systematic study of the effect of substitution within the β-amino acid framework indicates that both β2- and β3-amino acids catalyse the Hajos–Parrish–Eder–Sauer–Wiechert reaction with poor to reasonable levels of enantioselectivity. These results led to the evaluation of the conformationally constrained β-amino acid (1R,2S)-cispentacin, which catalyses the Hajos–Parrish–Eder–Sauer–Wiechert reaction with comparable or higher levels of enantioselectivity to L-proline.

  对β-氨基酸框架内取代效应的系统研究表明，β2-和β3-氨基酸催化Hajos–Parrish–Eder–Sauer–Wiechert反应的对映选择性较低至合理。这些结果促使对构象受限的β-氨基酸(1R,2S)-cispentacin进行评估，该氨基酸催化Hajos–Parrish–Eder–Sauer–Wiechert反应的对映选择性与L-脯氨酸相比相当或更高。

  The solid state and solution phase conformational preferences of a homologous series of beta-peptides derived from (S,S)-2-aminocyclopentanecarboxylic acid (transpentacin) have been investigated using a variety of spectroscopic and crystallographic techniques. These studies indicate that the hexamer and pentamer persist as a 12-helix in both the solid state and solution phase. Although the conformational traits of a 12-helix are exhibited by oligomers with as few as three residues in the solid state, in solution the trimer exists as an equilibrium of many alternative conformers whilst the tetramer has been shown to predominantly exist in either a 12-helix or a turn-type conformation.

  Conformationally restricted analogues of the central linker unit of bacterial methionyl tRNA synthetase (MRS) inhibitors have been prepared. The (IS,2R)-cyclopentylmethyl moiety was identified as the preferred cyclic linker, with significant diastereo- and enantio selectivity of activity. Combination of this linker with an optimal substituted aryl right-hand side has resulted in a compound with exceptionally good antibacterial activity against staphylococci and enterococci, including antibiotic resistant strains.

  The antifungal antibiotic (–)-(1R,2S)-2-aminocyclopentane-1-carboxylic acid (cispentacin)8 and its cyclohexane homologue 14 have been prepared utilizing the highly stereoselective conjugate addition of homochiral lithium N-benzyl-N-α-methylbenzylamide 5. The corresponding trans-β-amino acids 10 and 16 were also prepared via the selective epimerization of the cis-β-amino ester conjugate addition products
