19F-NMR spectra of MTPA-derivatized alcohols prepared via the Weinreb amide reduction (14a-i) and Swern (14a-ii) and Parikh-Doering (14a-iii) oxidation routes, followed by reduction of aldehydes to alcohols, Boc deprotection and coupling to MTPA-Cl. Insert: 19F-NMR of the alanyl-γPNA backbone (15a-ii) prepared by reductive amination of the Swern oxidation product followed by Boc deprotection and coupling to MTPA-Cl.
