A novel bowl-shaped macrobicyclic receptor has been prepared and is a particularly strong and selective receptor for Cbz-L-Ala-L-Ala-OH (–ΔGass = 25 kJ mol–1 at 293 K in CDCl3).
我们制备了一种新型碗状大双环受体,这种受体对 Cbz-L-Ala-L-Ala-OH 具有特别强的选择性(-ΔGass = 25 kJ mol-1 at 293 K in CDCl3)。

N-t-BOC-L-(Phosphonodifluoromethyl)phenylalanine benzyl ester (1) was prepared in 5 steps from N-t-BOC-L-tyrosine benzyl eser O-triflate (4). Compound 1 was further converted to derivatives 2 and 3 which are potentially suitable for peptide synthesis. Analogs 1 - 3 are non-hydrolyzable mimetics of O-phosphotyrosine.
