  摘要：

  尽管在使用木瓜蛋白酶的情况下，必须使用唯一的中性和大分子蛋白质 l-α-氨基酸（AA），但还是首次实现了 N-保护脱氢二肽甲酯（2）（Protect-ΔAA-AA-OMe）的酶水解。此外，C 组分 2 与含有脱氢缬氨酸（ΔVal）残基的 N 组分 α-氨基酸苯胺或脱氢二肽酯的反向酶偶联也获得了成功。因此，本研究表明，蛋白水解酶木瓜蛋白酶能够通过将 C 组份脱水肽与 N 组份 α-氨基酸、肽或脱水肽偶联，成为一种非常有用的肽合成工具。

• Proline-based dipeptides with two amide units as organocatalyst for the asymmetric aldol reaction of cyclohexanone with aldehydes

  A series of proline-based dipeptide organocatalysts with two amide units (1-16) have been developed and evaluated in the direct catalytic asymmetric aldol reactions of aldehydes with cyclohexanone. These catalysts showed good solubility in organic solvents compared with their corresponding carboxyl terminal dipeptides. The robust amide bond formation allowed structural modifications and fine tuning of catalyst properties by varying the stereo and electronic effects of the terminal amide to affect the ability of hydrogen bonding formation between the catalysts and the substrates. The reactions proceeded smoothly in high yields (up to 99%), enantioselectivities (up to 98% ee) and anti-diastereoselectivities (up to 99:1) in the presence of bifunctional organocatalyst 4 under the optimal reaction conditions.

  A series of alpha-amino amides derived from natural amino acids (alanine, valine, phenylalanine, isoleucine, and phenylglycine) have been synthesized and fully characterized. Their Ni(II) complexes prepared from Ni(acac)(2) catalyze the enantioselective conjugate addition of diethylzinc to chalcones in high yields and in good enantioselectivities (up to 84%). The side chain of the amino acid and the substituents in the amide nitrogen govern the enantioselectivity of the catalytic process. (c) 2008 Elsevier Ltd. All rights reserved.

  The enzymatic hydrolysis of N-protected dehydrodipeptide methyl esters (2) (Protect-ΔAA-AA-OMe) was first achieved, despite the requisite of the only neutral and large proteinic l-α-amino acid (AA) in the case using papain. Furthermore, the reverse enzymatic coupling of the C-component 2 with N-component α-amino acid anilides or dehydrodipeptide esters containing dehydrovaline (ΔVal) residue was also successful. Consequently, the present study suggests that the proteolytic enzyme papain is able to become a very useful tool for peptide synthesis by a coupling of the C-component dehydropeptide with N-component α-amino acid, peptide, or dehydropeptide.

  A highly enantioselective cyanation of imines (up to >99 % ee) has been developed using well-designed C2-symmetric hydrogen bonding catalysts. This catalytic system is distinguished by its low catalyst loading (S/C up to 1000), high efficiency, extremely broad substrate scope, scalability and mild reaction conditions.
