Key words

(±)-indolizomycin - McCluskey fragmentation - Wharton fragmentation

Significance

(±)-Indolizomycin has a unique structure containing a hemiaminal, where the bridgehead hydroxy group is flanked by a cyclopropane and an epoxide. Danishefsky and co-workers describe the first total synthesis of (±)-indolizo­mycin.

Comment

Annulation of diazo ketone D furnished indolizidine E. Subsequent McCluskey fragmentation and epoxidation set the stage for a Wharton fragmentation to furnish allylic alcohol I. Further elaboration gave (±)-indolizomycin.
