to replicate the biosynthesis of these compounds. Flinderoles A, B, and C, desmethylflinderole C, isoborreverine, and dimethylisoborreverine can each be synthesized in three steps from tryptamine. Furthermore, progress toward a concise enantioselective synthesis of flinderoles A, B, and C is described. This work includes enantioselective conjugate addition to an unprotected indole‐appended enone. Chirality
已经为抗疟疾inder生物碱定义了既可以立体控制又可以控制结构异构体形成的策略。事实证明,最近报道的细纹是从天然产物硼菜碱中提取的。通过在酸性条件下硼瑞林的二聚化,在体外还产生了绒毛的结构异构体,即boevereverines。该结果被认为可以重复这些化合物的生物合成。细绒球A,B和C,去甲基细绒球C,异硼苯丙氨酸和二甲基异硼苯丙氨酸可以分别由三色胺经三步合成。此外,描述了朝精简对映体合成细小分子A,B和C的进展。这项工作包括向未保护的吲哚附加的烯酮中添加对映体选择性共轭物。手征性,2015年27:14-17。©2013 Wiley Periodicals,Inc.
