compounds was subsequently shown by the preparation of orthogonally protected cis- and trans-indane-1,3-diamine using a Mitsunobu reaction. Both enantiomers of the trans isomer and a desymmetrized cis diastereomer were prepared in enantiopure form. Complete inversion of configuration during the Mitsunobu reaction was demonstrated by a combination of NMR techniques and molecular modeling. The utility
对映纯1,3-双官能化的茚满衍生物的有效化学合成已经实现。相应的顺式和反式N保护的氨基醇已成功地通过脂肪酶B乙酰化而分离,脂肪酶B是一种从南极假丝酵母分离的生物催化剂。以非常好的化学收率和ee值(> 99%)获得了所有可能的异构体。这些化合物的效用随后通过使用Mitsunobu反应制备正交保护的顺式和反式茚满-1,3-二胺得到了证明。反式异构体和去对称的顺式非对映体的对映体均以对映纯形式制备。通过结合NMR技术和分子模型,证明了Mitsunobu反应过程中构型的完全转化。
