An asymmetric synthesis of a chiral non-racemic (O-benzyl, O′-silyl) derivative of the latent C3v-symmetric tris(hydroxymethyl)methane (THYM*) and of the bis(hydroxymethyl)acetaldehyde (BHYMA*) in 6 steps, 38% overall yield and 7 steps, 36% overall yield, respectively, is described starting from the commercially available 4-nitrobenzoate derivative of 17. The method involves the Sharpless asymmetric
手性非外消旋(的不对称合成ø -苄基,O' -甲硅烷)衍生物的潜的Ç 3 v -对称三(羟甲基)甲烷(THYM *)和双(羟甲基)乙醛(BHYMA *)中从市售的4-硝基苯甲酸酯衍生物17开始分别描述了6步,总产率为38%和7步,总产率为36%。该方法涉及Sharpless不对称环氧化和区域选择性铜介导的环氧乙烷开环,这是关键步骤。
