Chiral non-racemic bicyclic lactams 2b,c, derived from (R)- and (S)-phenylglycinol, were used in the enantioselective synthesis of (−)-lupinine and 5-epitashiromine, respectively. The efficiency of the synthesis relied on the high diastereoselectivities of formation and reduction of compounds 2b,c.
衍生自(R)-和(S)-苯基甘氨醇的手性非外消旋双环内酰胺2b,c分别用于(-)-羽扇豆碱和5-表四代亚胺的对映选择性合成。合成的效率取决于化合物2b,c的形成和还原的高非对映选择性。
