seven-membered enone compound, the key intermediate of our previous synthesis of the inside-outside framework of 13-oxyingenol in racemic form, was achieved by using asymmetric cyclopropanation and reductive deoxygenation as key steps. 13-oxyingenol - asymmetric cyclopropanation - chiral aza-semicorrin ligand - reductive deoxygenation - intramolecular aldol reaction
通过使用不对称环丙烷化和还原性脱氧作为关键步骤,实现了七元烯酮化合物的对映选择性合成,这是我们先前合成的外消旋形式13-氧烯醇的内外骨架的关键中间体。 13-氧烯醇-不对称环丙烷化-手性氮杂-半corrin配体-还原性脱氧-分子内羟醛反应
