Birchreduction of arene carboxylic acids in the presence of chloroacetonitrile affords nitriles and their subsequent catalytic hydrogenation γ‐spirolactams in only 3 steps with excellent stereoselectivities. It is possible to control the degree of saturation by variation of the catalyst at different pressures. Thus, more than 15 new γ‐spirolactams have been synthesized from inexpensive starting materials
