reduced by NAD(P)H models (1-n-propyl-1,4-dihydronicotinamide (4) and Hantzsch ester(5)), in presence of magnesium perchlorate. One equivalent of the reductant reduces the substrates selectively to the corresponding 2-oxo-4-arylbutanoates (6,10a,b). An additional equivalent and higher temperature, converts ethyl 2-oxo-4-phenylbutanoate (6) to ethyl 2-hydroxy-4-phenylbutanoate (7). Reduction of ethyl
NAD(P)H模型(1-正丙基-1,4-二氢烟碱酰胺(4)和Hantzsch酯(5))还原了2-氧代-4-芳基-3-丁烯-1-酸乙酯1a – 1c,在高氯酸镁存在下。还原剂的一个当量选择性降低了底物相应的2-氧代-4- arylbutanoates(6,图10A,b)。额外的当量和更高的温度将2-氧代-4-苯基丁酸乙酯(6)转化为2-羟基-4-苯基丁酸乙酯(7)。Hantzsch酯在C 2 H 5中还原2-氧代-4-苯基-3-苯基-3-丁烯-1-油酸乙酯(1a)OD或通过汉奇酯-4,4- d 2用C 2 ħ 5 OH,导致直接转移的氢或氘,分别的,而不加扰同位素。这些结果已被解释为支持氢化物转移机理。
