    名称:
    3-Hydroxy-.alpha.-methyltyrosine progenitors, synthesis and evaluation of some (2-oxo-1,3-dioxol-4-yl)methyl esters
    摘要:
    The (5-methyl-2-oxo-1,3- dioxol -4-yl)methyl and (5-tert-butyl-2-oxo-1, 3- dioxol -4-yl)methyl esters of 3-hydroxy-alpha-methyltyrosine (methyldopa) were prepared and evaluated as progenitors of the amino acid. 1H NMR experiments reveal that the esters are converted cleanly to methyldopa and the corresponding alpha-diketone at pH 7.4, with the 5-methyl derivative undergoing hydrolysis faster than the 5-tert-butyl analogue. Bioavailability studies in dogs show that the esters, particularly the 5-methyl derivative, yield significant plasma levels of methyldopa. Both esters are orally effective antihypertensive agents in spontaneously hypertensive (SH) rats. These studies indicate that (2-oxo-1,3- dioxol -4-yl)methyl esters are viable prodrugs for the latentiation of methyldopa.

    摘要:
    醛在α位的有机催化光氧合反应通过烯胺催化进行,尽管烯胺应容易被单线态氧分别氧化为酰胺和羰基化合物。此外,基于实验和理论数据推测两性离子烯胺过氧化物中间体的形成。根据所用催化剂的不同,该反应可提供合适的收率(原位还原后)和(S)-或(R)-对映选择性的所需二醇。(S)-对映异构体在咪唑烷酮催化的反应中占主导地位,而脯氨酸酰胺确保了(R)立体异构体。DFT计算表明烯胺-氧复合物具有最低能量具有E, š -顺式构象的脯氨酰胺衍生物和E, š -反式的咪唑啉酮的催化剂,说明在光氧化反应的相反立体选择性。
