A novel conjugate hydrofluoroalkylation of α,β-unsaturated acyl-oxazolidinones is described. Using this method, enantiomerically pure β-trifluoromethylated amino acids were prepared. Trifluorovaline and trifluoroisoleucine were incorporated into peptides and found to show extremely low α-helix propensities.
描述了一种新颖的共轭氢氟烷基化α,β-不饱和酰基噁唑烷酮的方法。利用该方法,制备了手性纯的β-三氟甲基化氨基酸。三氟瓦林和三氟异亮氨酸被引入到肽中,发现其α-螺旋倾向极低。
