Abstract In products of Stevens 3, 2-rearrangement of ammonium salts containing alongside alkoxycarbon-ylmethyl also 3-phenyl-2-propynyl group an intramolecular 1, 5-hydride shift is observed resulting in immonium salts which transform into aminoesters of enamine structure. The hydrolysis of the latter provides the lower aliphatic aldehydes and the corresponding aminoesters. An acid treatment of the reaction mixture affords a mixture of ...
