herein, report the synthesis of 13C2-labeled natural products from the mugineic acid and avenic acid family. These phytosiderophores (“plant iron carriers”) are built up from non-proteinogenic amino acids and play a key role in micronutrient uptake in gramineous plants. In this work, two central building blocks are prepared from labeled starting materials (13C2-bromoacetic acid, 13C2-glycine) and further
我们在此报告了来自麦根酸和燕麦酸家族的13 C 2标记天然产物的合成。这些植物铁载体(“植物铁载体”)由非蛋白氨基酸组成,在禾本科植物的微量营养素吸收中发挥着关键作用。在这项工作中,两个中心结构单元由标记的起始材料( 13 C 2 -溴乙酸、 13 C 2 -甘氨酸)制备,并进一步用于我们最近报道的发散、支化合成策略,提供八种同位素标记的植物铁载体。所需的标记结构单元( 13 C 2 - l -烯丙基甘氨酸和相关的羟基化衍生物)分别通过对映选择性相转移催化和对映选择性和非对映选择性羟醛缩合与手性助剂制备,这两种方法本身对于其他合成路线都有潜在价值贴有标签的(天然)产品。
