Both the diastereomers of (±)-3-amino-2,2-dimethyl-1,3-diphenylpropan-1-ol were synthesized starting from a common intermediate, namely, β-hydroxy oxime 6. Diastereoselective reduction with NaBH4/TiCl4 and H2-Pd/C provided syn- and anti-isomers, respectively. Good overall yield and selectivity were realized using a simple protocol.
(±)-3-氨基-2,2-二甲基-1,3-二苯基丙-1-醇的两种非对映异构体都是从一个常见的中间体β-羟基肟6合成的。用NaBH 4 / TiCl 4和H 2 -Pd / C进行非对映选择性还原分别提供了顺式和反式异构体。使用简单的方案即可实现良好的总收率和选择性。
