Contrary to a published report, C-alkylation of methyl hippurate requires two equivalents of base. The choice of additive (TMEDA or HMPA) influences the result. Deuteration of the enolate gives results which depend on both the deuterium source and the nature of the additive.
与已发表的报告相反,马尿酸甲酯的C-烷基化需要两个当量的碱。添加剂(TMEDA或HMPA)的选择会影响结果。烯醇盐的氘化结果取决于氘源和添加剂的性质。
