(S)-(+)-1-Amino-3-phenyloxy-2-propanol, (R)-(−)-2-amino-1-phenylethanol, (S)-(+)-1-amino-2-propanol, (1S,2S)-(+)-2-aminocyclohexanol and (1S,2S)-(+)-1,2-diaminocyclohexane were resolved using dehydroabietic acid. It was shown that good to high enantiomeric purity, between 81∼>99% ee, was obtained and that dehydroabietic acid could be easily and efficiently recovered in a reusable form.
(S)-(+)-1-氨基-3-苯氧基-2-丙醇,(R)-(-)-2-氨基-1-苯基乙醇,(S)-(+)-1-氨基-2-使用脱氢松香酸拆分丙醇,(1 S,2 S)-(+)-2-氨基环己醇和(1 S,2 S)-(+)-1,2-二氨基环己烷。结果表明,获得了良好的至高的对映体纯度,ee在81-> 99%ee之间,并且脱氢松香酸可以容易地和有效地以可重复使用的形式回收。
