(R) - and (S) asymmetric synthesis method from imino ketone of - aryl ethanolamine

摘要

(57) Abstract Enantiomer choice reduction manner to the amino alcohol of amino ketone is disclosed. This manner utilizes with kiraru 1,3,2 okisazabororu as a borane reduction operation material and a catalytic converter as the reduction operation material. This manner is applied to high optical genuine synthesis at high yield from the 5 acetyl methyl salicylate of R arubuteroru.
