  Benzotriazole-Assisted Solid-Phase Assembly of Leu-Enkephalin, Amyloid β segment 34−42, and other “Difficult” Peptide Sequences

  摘要：

  Microwave-assisted solid-phase syntheses of six "difficult" peptides, H-VVSVV-NH(2) (3), H-VVVSVV-NH(2) (4), H-VIVIG-OH (5), H-TVTVTV-NH(2) (6), H-VKDGYI-NH(2) (7), and H-VKDVYI-NH(2) (8), were achieved utilizing N-(Fmoc-(alpha-aminoacyl)benzotriazoles. Extension to the syntheses of Leu-enkephalin (9) and amyloid-beta (34-42) (10) demonstrates that this strategy comprises an efficient route to new and known "difficult" peptides.

  The transprotection of N-Fmoc-cysteine containing di- and tripeptides possessing a free SH group to produce the corresponding S-Fm-cysteine di- and tripeptides bearing a free amino group is accomplished efficiently with DBU in dry THF. The N-Fmoc to S-Fm transformation mechanism is discussed. S-Fm-Cysteine di- and tripeptides readily form amide bonds on coupling with N-(Pg-α-aminoacyl)benzotriazoles and N-(Pg-α-dipeptidoyl)benzotriazoles to give larger peptides.

  在干燥的四氢呋喃中，用 DBU 可以高效地对含有游离 SH 基团的 N-Fmoc-半胱氨酸二肽和三肽进行反保护，生成相应的含有游离氨基的 S-Fm-半胱氨酸二肽和三肽。本文讨论了 N-Fmoc 到 S-Fm 的转化机理。S-Fm-Cysteine 二肽和三肽在与 N-(Pg-α-氨基酰基)苯并三唑和 N-(Pg-α-二肽酰基)苯并三唑偶联时很容易形成酰胺键，从而得到更大的肽。

  We describe the efficient synthesis of 4,7,8,10-tetrasubstituted-((( 4S 10aS)-3-oxo -3,4,10,10a-tetrahydrobenzo[4,5]imidazo[1,2-a]pyrazin-2(1H)-yl)alkyl)amides on solid phase via tandem N-acyliminium ion cyclization-nucleophilic addition reactions. The synthesis proceeded with complete stereocontrol of a newly formed stereogenic center provided crude material of high purity and used commercially available building blocks under mild reaction conditions.
