1-phenylethanol is described for the first time. The enzymatic hydrolysis resolution
of 1-phenylethyl esters with different chain-lengths in the prence of Candida antarctica lipa B in mini-emulsion media was shown to be significantly controlled
by temperature. In this system, the direct effect of temperature on the mini-emulsion size was obrved. For the longer 1-phenylethyl ester, 1-phenylethyl dodecanoate, the enzymatic resolution was promoted exclusively at low temperatures. The preparative mini-emulsion enzymatic reaction of 1-phenylethyl dodecanoate at 4°C afforded the isolation of (R)-phenylethanol with a yield of 36 % with an ee of 99 %. (S)-Phenylethanol was isolated with a 51 % yield with an ee of 79 %.爱人体摄影
