“CO 2 fixation” has been achieved, under normal pressure at room temperature without a catalyst, by means of the title reaction. The five‐ and six‐membered heterocycles 1 and 2 , respectively, are formed in 40–70% yield. Longer reaction time and the addition of Cs 2 CO 3 increases the yields to 60–90% (R 1 = H, alkyl, aryl; R 2 = H, alkyl; R 3 = H, CH 2 Aryl).
