Protection optional: The title reaction strategy is used to prepare 1,2‐diols with complete control of their absolute and relative stereochemistry. The method tolerates free and Me‐/Bn‐/TBS‐protected alcohol functionalities, and its diastereoselectivity is controlled by the stereochemistry of the ligands/catalysts used. Protected 1,2,3,4‐tetraols are synthesized by iterative applications of the strategy
可选的保护:标题反应策略用于制备1,2-二醇,并完全控制其绝对和相对立体化学。该方法耐受游离的和Me- / Bn- / TBS保护的醇官能团,其非对映选择性受所用配体/催化剂的立体化学控制。受保护的1,2,3,4-四醇是通过该策略的迭代应用合成的。
