2-苯基丙醛制备

1.由乙酰苯和氯乙酸乙酯在碱性条件下缩合而成。
2.由甲基苯基乙二醇在常压下蒸馏而得。

3.制法：

3-苯基-2,3-环氧丁酸乙酯（4）：于装有搅拌器、温度计的反应瓶中，加入乙酰基苯（2）60g（0.5mol），氯乙酸乙酯（3）61.5g，100mL用金属钠干燥的苯。冰水浴冷却，搅拌下于2h加入氨基钠23.6g搅拌。分出有机层，水层用100mL苯提取。合并有机层，水洗两次，再用含5mL醋酸的100mL水洗涤。无水硫酸镁干燥，蒸馏除苯，减压分馏，收集111～114℃/0.4kPa的馏分，得3-苯基-2,3-环氧丁酸乙酯（4）67g，收率65%。2-苯基丙醛（1）：于装有搅拌器、温度计的反应瓶中，加入150mL无水乙醇，分批加入金属钠7.6g（0.33mol），制成乙醇钠的乙醇溶液。慢慢加入化合物（4）66.5g，冷却至15℃，再慢慢加入水6mL，反应放热，并很快析出钠盐。混合物反应过夜，过量析出的钠盐，用少量乙醇洗涤，再以乙醚洗涤。将盐加入稀盐酸中（由28mL浓盐酸和150mL水配制），蒸汽浴加热反应1.5h。有二氧化碳逸出，并有油状物析出。冷却，以苯提取。水洗，蒸出苯，再减压蒸馏，收集90～93℃/1.33kpa的馏分，得2-苯基丙醛（1）30g，收率70%。

Reductive activation of dioxygen by a myoglobin reconstituted with a flavohemin.

J. Am. Chem. Soc. 124(38) , 11234-5, (2002)

We successfully converted myoglobin, an oxygen-storage hemoprotein, into an oxygen-activating hemoprotein like cytochrome P450s by replacing the native hemin with the artificially created flavohemin. ...

Investigating the role of 2-phenylpropenal in felbamate-induced idiosyncratic drug reactions.

Chem. Res. Toxicol. 17(12) , 1568-76, (2004)

Felbamate (2-phenyl-1,3-propanediol dicarbamate, FBM) can cause aplastic anemia and hepatotoxicity. The mechanism of FBM-induced toxicities is unknown; however, it has been proposed that 2-phenylprope...

Synthesis and in vitro reactivity of 3-carbamoyl-2-phenylpropionaldehyde and 2-phenylpropenal: putative reactive metabolites of felbamate.

Chem. Res. Toxicol. 9(8) , 1225-9, (1996)

We propose that 3-carbamoyl-2-phenylpropionaldehyde is an intermediate in the metabolism of felbamate, an anti-epileptic drug with a unique profile of the therapeutic activity, and undergoes a cascade...
