contributed to the knowledge of the mechanism of this oxidative rearrangement. On the other hand, the reduction of 1‐methylpyridinium iodide with sodium borohydride and with potassium cyanide present since the start of the reaction in a two layer ether‐water system, gave 2‐cyano‐1‐methyl‐4‐piperideine. This was transformed into (±)‐anatabine by the same sequence of reactions used for the synthesis of (±)‐isoanatabine
