direct reductive amination protocol of camphor and fenchone was developed. Scope and limitations of this protocol were studied. Primary amines react with high stereoselectivity while secondary cyclic amines lead to a mixture of endo‐(major) and exo‐(minor) adducts with a good to moderate yields.
开发了
樟脑和fenchone的直接还原胺化方案。研究了该协议的范围和局限性。
伯胺具有很高的立体选择性,而仲环胺则可生成内(主要)和外(次要)加合物的混合物,产率中等至中等。
