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

  摘要：

  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。

  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.

  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.
