our recent report on the enantioselective synthesis of syn and anti 1,2-diols from oxalyl-di-(N-methyl-N-methoxyamide), an unfortunate sample inversion for 13C NMR analysis led us to an incorrect attribution of their relative configurations. We report now the correction of the configurations of these diols by X-ray analysis and chemical correlation to two known natural products, goniobutenolides A
在我们最近的有关从草酰二-(N-甲基-N-甲氧基酰胺)对映异构体合成顺式和反式1,2-二醇的报告中,不幸的13 C NMR样品反演结果使我们误解了其相对分子质量配置。我们现在报告通过X射线分析和与两种已知的天然产物goniobutenolides A和B的化学相关性对这些二醇的构型进行校正。
