Retrosynthetic analysis of the heptacyclic ring structure of nominine (3), a representative member of the hetisine family of alkaloids, is not for the faint of heart. David Y. 334905-81-6 manufacturer…
Synthesis: Part One of Three We last reviewed organic synthesis applications of the Grubbs reaction on April 19, 2004. The (relatively) robust nature of the commercially-available catalyst and its commercial…
(-)-Terpestacin (3), isolated from Arthrinium sp. Buy157327-48-5 FA1744, inhibits the formation of syncytia by HIV-infected T cells. PMID:26644518 A key step in the total synthesis of 3 reported (J. Buy2-Chloro-5,7-difluorobenzothiazole…
The guanacastepenes, of which guanacastepene E (3) is representative, initially elicited excitement because of their activity against drug resistant bacterial strains. Although the systemic toxicity of the guanacastepenes has cooled…
