Enantiopure 3,7-diazabicyclo[3.3.1]nonane derivatives 4 and 5, potential precursors of quinolizidine alkaloids, were synthesised in high yields, starting from the biocatalytic asymmetrization of σ-symmetric 3,5-disubstituted piperidines. Their application to the total synthesis of the new pharmacologically active compounds 3 are also described.
对映体纯的3,7-二氮杂双环[3.3.1]壬烷衍生物4和5,即喹喔啉生物碱的潜在前体,从σ对称3,5-二取代哌啶的生物催化不对称化开始,以高收率合成。还描述了它们在新的药理活性化合物3的全合成中的应用。
