Synthesis of a complete series of C-4 fluorinated Phe-Gly mimetics was written by Berts, Wei;Luthman, Kristina. And the article was included in Tetrahedron in 1999.HPLC of Formula: 87694-53-9 This article mentions the following:
The complete series of allylic monofluorinated derivatives I (R1 = H, R2 = F; R1 = F, R2 = H) and difluorinated derivatives II of Boc-Phe-Gly-OMe has been synthesized using facile methods. The saturated derivatives of I and II were also synthesized. Diastereomeric allylic alc. derivatives were used as key intermediates. Cis- and trans-aziridine derivatives were synthesized in high yields from the diastereomeric alcs. using Mitsunobu conditions. The aziridines were treated with diethylaminosulfur trifluoride (DAST) at room temperature, which resulted in stereoselective ring openings yielding the monofluorinated derivatives The difluorinated isostere was synthesized from the 绾?keto ester derivative using DAST. In the experiment, the researchers used many compounds, for example, (S)-tert-Butyl (1-(methoxy(methyl)amino)-1-oxo-3-phenylpropan-2-yl)carbamate (cas: 87694-53-9HPLC of Formula: 87694-53-9).
(S)-tert-Butyl (1-(methoxy(methyl)amino)-1-oxo-3-phenylpropan-2-yl)carbamate (cas: 87694-53-9) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.HPLC of Formula: 87694-53-9
