configurations of a series of primary alcohols possessing a branched methyl group at C2 position were examined on the basis of a modified Mosher's method proposed by Minale et al. It was revealed that in many cases the absolute configurations at C2 were assignable from the chemical shift differences of geminal protons of the methylene attached to the ester linkage in the alpha-methoxy-alpha-trifluoromethylphenylacetyl
在Minale等人提出的改进的Mosher方法的基础上,研究了一系列在C 2位具有支链甲基的伯醇的绝对构型。揭示了在许多情况下,在C2处的绝对构型可根据与α-甲氧基-α-三氟甲基苯基乙酰基(MTPA)衍生物中的酯键相连的亚甲基的双键质子的化学位移差异进行分配。描述了该方法的范围和局限性。
