実験手順

Methyl (2R)-3-(3-hydroxyphenyl)-2-methylpropanoate (62) and methyl (2S)-3-(3-hydroxyphenyl)-2-methylpropanoate (63). Racemic ethyl 3-(3-hydroxyphenyl)-2-methylpropanoate 62.C (0.40 g) was separated by ChiralPak OJ-H column, eluted with 10% isopropanol in hexane to give the separated enantiomers; (R)-ethyl 3-(3-hydroxyphenyl)-2-methylpropanoate and (S)-ethyl 3-(3-hydroxyphenyl)-2-methylpropanoate 62 and 63. MS ESI (pos.) m/e: 209.1 (M+H)+.
