| Abstract: | A new method for the stereoselective synthesis of highly substituted (1E,3E)‐2‐sulfonyl‐1,3‐dienes from N‐propargylic sulfonohydrazone derivatives has been developed via copper(I)‐catalyzed 3,3] rearrangement and highly regioselective migration of the sulfonyl group. |
| Keywords: | migration of the sulfonyl group N‐propargylic sulfonohydrazone [3 3] rearrangements (1E 3E)‐2‐sulfonyl‐1 3‐dienes |
