(S)-2-[(R)-Fluoro(phenyl)methyl]oxirane is a new, synthetic, yet enantiopure, chiral resolution reagent, readily obtained from enantiopure (2S,3S)-phenylglycidol, that reacts with a variety of alpha-chiral primary and secondary amines in a straightforward manner through a regioselective ring-opening. Diastereomeric products are easily identified and quantified by (19)F, (1)H, and (13)C NMR and by HPLC
(S)-2-[(R)-氟(苯基)甲基]环氧乙烷是一种新的,合成的但对映体纯的手性拆分试剂,可轻松从对映纯(2S,3S)-苯基缩水甘油中获得,与多种α通过区域选择性开环以直接的方式-手性伯胺和仲胺。非对映异构产物易于通过(19)F,(1)H和(13)C NMR以及HPLC进行鉴定和定量,这使得该氟化化合物成为分析胺类规模混合物的最通用试剂。[反应:看文字]
