Under (not so much) pressure: A general method for the hydrogenation of tertiary and secondary amides to amines with excellent selectivity using a bimetallic Pd–Re catalyst has been developed. The reaction proceeds under low pressure and comparatively low temperature. This method provides organic chemists with a simple and reliable tool for the synthesis of amines.

Take a walk on the wild side: A novel benzylClaisen cascade rearrangement of keteniminium salts is described. The reaction leads to α‐arylated lactones under metal‐free conditions (top scheme; Tf=trifluoromethanesulfonyl). It is further demonstrated that the cationic intermediates involved can be steered away from pericyclic reaction manifolds into powerful ionic shifts through reaction design (bottom
Unexpected Electrophilic Rearrangements of Amides: A Stereoselective Entry to Challenging Substituted Lactones

Surprise, surprise! An unexpected skeletal rearrangement was developed into a chemo‐ and stereoselective synthesis of α‐allyl and allenyl lactones with challenging substitution patterns (see scheme; EWG=electron‐withdrawing group). The generality, unique features, and synthetic potential of this reaction were probed and a mechanism was proposed.
