Unexpected electrophilic rearrangements of amides: A stereoselective entry to challenging substituted lactones
"Chemical Equation Presented" Surprise, surprise! An unexpected skeletal rearrangement was developed into a chemo- and stereoselective synthesis of aallyl and allenyl lactones with challenging substitution patterns (see scheme; EWC = electron-withdrawing group). The generality, unique features, and synthetic potential of this reaction were probed and a mechanism was proposed.
