Description
メトキシ酢酸イソプロピル(IPMA)(19.8g、0.15 mol)とNovozyme 435 (500mg)を4-(1-アミノエチル)安息香酸メチル1(17.9g、0.1mol)のトルエン(150ml)溶液に加え、室温で撹拌した。24時間後のHPLC分析は、全てのR-1がR-アミドR-2に変換され未反応のS-アミンS-1のみが検出可能となったことを示していた。酵素を、珪藻土を通して吸引しながら濾別し、フィルター上の残渣をトルエン(20 ml) で洗浄し、硫酸(38%水溶液6.45g、25 mmol)を撹拌しながら濾液に加えた。多量の白色沈殿が分離した。沈殿した塩を吸引濾過し、トルエン(2 x 20 ml)で洗浄し、フィルター上の残渣を水(10 ml)から再結晶した。8.9 g (78%) のS-1硫酸塩を結晶性白色固体として単離した。S-アミンS-1はHPLC分析によるとエナンチオピュアであった。融点: 280℃ (分解)、旋光度:[α]D= -3.5° (c=1、H2O)。
アミン (1):

1H-NMR (400 MHz, D2O) δ= 1.65 (d, J= 7 Hz, 3H); 3.95 (s, 3H), 4.65 (q, J= 7 Hz, 1H), 7.60および8.10 (AA’, BB’系, JAB= 10.7 Hz, 4H)。
1H-NMR (400 MHz, CDCl3) δ= 1.55 (d, J= 7 Hz, 3H); 3.42 (s, 3H), 3.88および3.93 (AB 系, JAB= 15 Hz, 2H), 3.90 (s, 3H), 5.23 (sept, J= 7 Hz, 1 H), 6.80 (d (broad), J= 7 Hz, 1H), 7.40および8.03 (AA’, BB’ 系, JAB= 10.7 Hz, 4H)
