D-galactose or D-ribose derivatives. The selection of the starting material depends, therefore, only on its availability. The interchangeability of the synthetic routes is especially important when rare sugars have to be used in the synthesis.
                                    从

生物开始,通过两种独立的途径获得了
烯丙醇4(一种用于制备脱氮氮
磺胺(2)的手性合成子)。因此,原料的选择仅取决于其可用性。当必须在合成中使用稀有糖时,合成路线的互换性尤为重要。
