(3S,4S)-N-Benzyl-3,4-dihydroxypyrrolidine 1 has been used as a building block for new enantiopure macrocyclic polyesters. Two different synthetic approaches are presented leading to complementary results. The structure of the macrocycles synthesized has been confirmed by NMR spectroscopy and FAB mass spectrometry, and that for dimer 8 has been confirmed by X-ray analysis.
(3S,4S)-N-苄基-3,4-二羟基吡咯烷 1 被用作新的对映体纯大环聚酯的构建基块。两种不同的合成方法产生了互补的结果。合成的大环的结构已通过核磁共振光谱和 FAB 质谱法得到证实,二聚体 8 的结构已通过 X 射线分析得到证实。
