The dopaâsulfinylnorvaline component of ustiloxins A and B has been prepared using an Evans salenâAl-catalysed aldol reaction with a 6-mercaptoisovanillin derivative, followed by incorporation of the norvaline group and asymmetric oxidation of the resulting sulfide to give the corresponding sulfoxide.
乌司替罗星 A 和 B 的多巴亚磺酰正缬氨酸成分是通过埃文斯-萨伦-阿尔催化的醛醇反应与 6-巯基异香兰素衍生物制备的,随后加入正缬氨酸基团,并对生成的硫化物进行不对称氧化,得到相应的亚砜。
