Here is a one-step transformation that I think few, perhaps not even Corey,* would come up with upon a traditional retrosynthetic analysis.
A and B are everyday organic reagents. The solvent is DCM and the temperature is around 0 °C. No metals, complexes or weird oxidation level crap. So – go ahead and name A and B!
Remember I have this Stuxnet 3.5 beta spyware installed on all of your computers that smell out and report the use of SciFinder and Reaxys. Likewise through your webcam, Vogel, March, Paquette and Larock are detected, to name a few.
Kudos to FA, my fellow grad student, who back in the days included this example in his thesis (also recognized by my software).
* Retract that. Corey would have.
