Ring opening of 2-cyano-3-phenylaziridine and 2-amido-3-phénylaziridine by HF/pyridine was found to give 2-amino-3-fluorophenylpropionitrile (IV) and 2-amino-3-fluorophenylalanamide (VII) respectively. 3-fluorophenylalanine (V) could be obtained by an acidic hydrolysis of (IV) or (VII) whereas isopropyl-3 fluorophenylalanate (VI) was isolated by esterification of (V) or by heating (IV) with iso-propanal-12
发现2-氰基-3-苯基氮丙啶和2-酰胺基-3-苯基氮丙啶通过HF /吡啶的开环分别得到2-氨基-3-氟苯基丙腈(IV)和2-氨基-3-氟苯基丙酰胺(VII)。3-氟苯丙氨酸(V)可通过(IV)或(VII)的酸性水解获得,而异丙基-3氟苯丙氨酸盐(VI)可通过(V)的酯化或与异丙醇-12 NHCl加热(IV)来分离在回流下。
