Synthesis and Characterization of Optically Pure Gamma-PNA Backbones by SIBX-Mediated Reductive Amination

Chiral peptide nucleic acid (PNA) is a derivative of regular PNA by introducing a chiral center to its backbone, and is known to bind more strongly to DNA or RNA than regular PNA. In particular, in the case of a γ-backbone, the L isomer stabilizes the PNA/DNA duplex, and the D-isomer has the opposite effect. Therefore, the synthesis of an optically pure γ-backbone is very important. Here, we report a novel synthetic strategy for the suppression of epimerization during the synthesis of the γ-PNA backbone. A stabilized form of 2-iodoxybenzoic acid (SIBX) was used as an oxidative reagent in the key intermediate of the N-Boc-amino acetaldehyde synthesis. This paper reports (1) the synthesis and comparison of three different γ-PNA backbones (lysine, alanine, and glutamate) by three different synthetic routes (SIBX, lithium aluminum hydride, and Red-Al) and (2) the determination of chiral purity from their derivative compounds. The enantiomeric excess purity of SIBX-mediated γ-PNA backbones was determined to be more than 99.4%, as ascertained by the high-performance liquid chromatography (HPLC) chromatogram on a standard RP-C18 column. It is comparatively higher than that of the other methods examined in this work.

A direct and efficient stereoconservative procedure for the selective oxidation of N-protected β-amino alcohols

An efficient, very simple and eco-friendly procedure has been developed for the synthesis of highly enantioenriched α-amino aldehydes by IBX-mediated oxidation of the corresponding β-amino alcohols. The procedure has been applied to a wide range of substr
