Abstract A safe and efficient process has been developed for the multigram synthesis of 1-(3-hydroxy-4-methoxyphenyl)ethane-1,2-diol (iso-MHPG) 2, via osmium-catalysed dihydroxylation of 3-benzyloxy-4-methoxystyrene 5, and subsequent debenzylation. The methodology has been extended to an asymmetric synthesis of both enantiomers.
摘要 通过锇催化的 3-苄氧基-4 的二羟基化,已开发出一种安全有效的方法,用于多克合成 1-(3-羟基-4-甲氧基苯基)乙烷-1,2-二醇 (iso-MHPG) 2 -甲氧基苯乙烯 5,然后脱苄基。该方法已扩展到两种对映异构体的不对称合成。
