Enantioselective Synthesis of Sealutomicin C. [PDF]

J Am Chem Soc
The sealutomicins are a family of anthraquinone antibiotics featuring an enediyne (sealutomicin A) or Bergman-cyclized aromatic ring (sealutomicins B – D). Herein we report the development of an enantioselective organocatalytic method for the synthesis of dihydroquinolines and the use of the developed method in the total synthesis of sealutomicin C ...

Total Enantioselective Synthesis of (‐)‐Cytisine. [PDF]

ChemInform, 2004
[reaction: see text] The first total enantiosynthesis of the biologically active alkaloid (-)-cytisine is reported, featuring a ruthenium-catalyzed RCM reaction as the key step. The approach relies on readily available cis-piperidine-3,5-dimethanol monoacetate as the chiral building block, and it is suited for achieving the target compound in both ...

Enantioselective Synthesis of Azamerone [PDF]

Journal of the American Chemical Society, 2018
A concise and selective synthesis of the dichlorinated meroterpenoid azamerone is described. The paucity of tactics for the synthesis of chiral organochlorides motivated the development of unique strategies for accessing these motifs in enantioenriched forms.

Highly efficient synthesis of the tricyclic core of Taxol by cascade metathesis [PDF]

, 2014
An efficient enantioselective synthesis of the ABC tricyclic core of the anticancer drug Taxol is reported. The key step of this synthesis is a cascade metathesis reaction, which leads in one operation to the required tricycle if appropriate fine-tuning ...
