All in the name, this one. Obviously a bisamide, so even the undergrads would get the major disconnections in this one! They put the spiroketal in very nicely though, alkylating and hydrogenating to give the desired product in 83% over two steps.

although it looks quite simple, biological activity is impressive though. Nice work was done to identify its mechanism of action. Some other syntheses are impressive also
alkyne proton is missing, i guess.
Damn! You got me – however, the wonders of photoshop never cease! That Add-A-Proton-To-An-Acetylene function is ace.
I seriously doubt how this work got to JACS. Comparing to Kozmin’s work (published in JACS 2004), it has more steps, lower total yield. More ironically, it basically copied the end-game reactions, even the protecting groups! Also, it still said the target was PKC in the introduction, while the mode of action studies were already published!
“the mode of action studies were already published”
Decemeber 2005 in NatChemBiol, this one is published in April 2006.
I think you’re “technically” right, NoName
