An attractive approach to valuable yet synthetically challenging benzo[b]azepines was established via palladium(II)/Lewis acid cocatalyzed oxidative [5 + 2] annulation of readily available 2-alkenylanilines and propargylic esters. The protocol features mild reaction conditions and good functional group tolerance, constituting an array of benzo[b]azepines in yields of 30-75%.

A combination of IPrAuNTf2 as catalyst in the presence of Selectfluor has been successfully used for the high yielding synthesis of α-fluoroenones via 1,3-acyloxy rearrangement of propargyl acetates followed by Csp2-F bond formation,
Gold-catalyzed efficient preparation of linear α-haloenones from propargylic acetates

Versatile linear α-iodo- and α-bromoenones are prepared efficiently from readily accessible propargylic acetates using 2 mol % of Au(PPh3)NTf2. This reaction is easy to execute and has broad substrate scope. Good to excellent Z-selectivities are observed in the cases of propargylic acetates derived from aliphatic aldehydes.
