A TMSOTf promoted addition of an N-tert-butanesulfinyl α-imino ester to five-membered aromatic heterocycles furnishes optically active heteroaromatic glycine derivatives with moderate-to-good yield in diastereomeric ratios up to 99 %. The absolute configuration of two of the addition products were solved by X-ray analysis. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
TMSOTf 促进了 N-叔丁烷亚磺酰基 α-亚氨基酯向五元芳族杂环的加成,提供了具有中等至良好收率的光学活性杂芳族甘氨酸衍生物,非对映体比例高达 99%。两种加成产物的绝对构型通过 X 射线分析求解。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
