    • As is often the case with discovery in synthesis, this particular transformation was serendipitously observed while attempting something different. Then graduate student Brian Stoltz working with postdoctoral student Hans-Juergen Dietrich was attempting to perform an OH insertion with allylic alcohol substrates. Our interest in the latter was actually stimulated through discussions at Yale Chemistry happy hours with a postdoctoral student from Harry Wasserman's group, Dr. Steve Coats and a good friend of his, Dr. Martin Osterhaut, who was working at Bayer in West Haven, CT. Steve and Martin, who had both spent time in Al Padwa's group, proved to be valuable sources of information regarding rhodium promoted reactions of diazoketones. The chemistry discovered by Stoltz and Dietrich played a central role in four Ph.D. theses from my group (Stoltz, Pflum, Petsch, and Moniz) and clearly continues to occasionally impact our thinking.

    • The enantiomeric ratio was determined by chiral HPLC analysis of azide (+)-3 (ChiralPak IC column, 99:1 hexanes/isopropanol). The absolute stereochemistry was initially assigned in accord with observations in previous rhodium-initiated Claisen rearrangements (see Ref. 16b) and is consistent with that expected for the production of (+)-norsecurinine.
