Indole alkaloid synthesis

Posted by naturalproductman on July 15, 2014

Corey Stephenson and colleague at the University of Michigan have reported in JACS on the synthesis of pseudotabersonine. A mental roadblock for me was when I was looking at the paper, I was trying to find the structure of catalyst 5, which was the iridium catalyst used for a ring opening reaction, but just found the number 5 in the scheme. Within the text of the paper however it says Ir(dF(CF3)ppy)2(dtbbpy)PF6, which was cited with a Sigma Aldrich catalog number.

Dimerization, electrochemically

Posted by naturalproductman on April 18, 2014

Phil Baran and co-workers reported in JACS on a synthesis of dixiamycin via electrochemical dimerization. I usually think of Kevin Moeller from Washington University in St. Louis when I see electrochemical reactions.
