total syntheses of (+)-streptazolin 1 and its more stable dihydro derivative 2 were accomplished via an intramolecular aldol condensation strategy starting from readily available aminocyclopentenol (−)-7. The synthetic sequence included reductive amination, stereoselective epoxidation, intramolecular aldol (and condensation) reaction, and Wittig reaction. The overall yield for dihydro derivative 2 from
简明的(+)-链霉唑啉1及其更稳定的二氢衍生物2的总合成是通过分子内羟醛缩合策略完成的,从容易获得的氨基环戊烯醇(-)- 7开始。合成序列包括还原胺化,立体选择性环氧化,分子内羟醛(和缩合)反应和Wittig反应。来自氨基环戊烯醇(-)- 7的二氢衍生物2的总产率为约7%,共14步。
