reaction of anilines and phenylacetaldehydes in the presence of chiral phosphoric acid afforded optically active 1,2-trans, 2,3-cis 1,3-diaminotetralins in high yields with excellent diastereo- and enantioselectivities. The trans/cis product was readily isomerized to a trans/trans stereoisomer with no significant loss of enantiomeric purity.
在手性磷酸的存在下苯胺和苯乙醛的反应以高收率提供了光学活性的1,2-反式,2,3-顺式1,3-二氨基四氢化萘,具有出色的非对映选择性和对映选择性。所述反式/顺式产物容易异构化为反式/反式立体异构体与对映体纯度的无显著损失。
