The Grubbs Reaction in Organic
Chemexpress 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…
The Sorensen Synthesis of (-)-Guanacastepene E
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…
The Trost Synthesis of (-)-Terpestacin
(-)-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 Crimmins Synthesis of (+)-SCH 351448
The symmetrical macrodiolide (+)-SCH 351448 (4) is the only known selective activator of transcription from the low density lipoprotein receptor. The highly convergent synthesis of 4 from 1 and 2…
The Overman Synthesis of (-)-Sarain A
Larry E. Overman of the University of California, Irvine has recently (Angew. Chem. Int. PMID:25959043 2,4-Bis(trifluoromethyl)benzaldehyde supplier Ed. 2006, 45, 2912. DOI: 10.1002/anie.200600417)described the first total synthesis of the antibiotic…
The Clark Synthesis of Vigulariol
Vigulariol (3), isolated from the octocoral Vigularia juncea (Pallas), is active against human lung adenocarcinoma cells (IC50 = 18 nM). A key step in the synthesis of 3 reported (Angew.…
The Pettus Synthesis of (+)-Rishirilide B
(+)-Rishirilide (4), an inhibitor of α2-macroglobulin, a tetrameric serum glycoprotein that is an irreversible protease inhibitor, has a deceptively simple structure. Thomas R. R. Pettus of the University of California…
The Padwa Synthesis of Aspidophytidine
Albert Padwa of Emory University has developed (Org. PMID:23664186 Fmoc-Ala-OH supplier Lett. 2006, 8, 3275. DOI: 10.1021/ol061137i) a productive approach to fused indole alkaloids such as aspidophytine (3), based on…
The Nakada Synthesis of (+)-Digitoxigenin
The total synthesis of steroids such as (+)-digitoxigenin (3) has been studied for more than sixty years, yet it has never been thought that such studies would lead to a…
The Nicolaou Synthesis of Platensimycin
The report last year by scientists at Merck of an antibiotic, platensimycin3, with a novel mechanism of action has led to much effort toward the total synthesis of this degraded…
