Anti-Markovnikov oxidation of allylic esters

Ben Feringa and co-workers at the University of Groningen have reported in ACIE on a palladium catalzyed anti-Markovnikov oxidation of allylic esters.  This is the opposite of what we see in a Wacker-Tsuji process.

Towards PF-1018

Dirk Trauner and co-workers at have reported in Organic Letters on a Stille-Diels Alder cascade approach towards PF-1018.

Mitsunobu with a catalytic twist

Hiroyuki Ishibashi and co-workers at Kanazawa University have reported in ACIE on a Mitsunobu reaction where they use an iron catalyst and oxygen to regenerate the active azo reagent.

ACIE paper

Kingianin synthesis

Michael Sherburn and co-workers from Australian National University have reported in ACIE on the synthesis of kingianins A, D, and F from a poly-yne precursor.  Ledwith-Weitz salt was used to promote a Diels-Alder dimerization.

Spontaneous Diels-Alder

Craig Merlic and co-workers from UCLA have reported in Organic Letters on a spontaneous transannular Diels-Alder when they used a palladium catalyzed C-C bond forming strategy.
