Reaction of 2,2‐dinitro‐1,3‐propanediol (1) with oxalyl dichloride or malonyl dichloride in refluxing ether led to the formation of cyclic dinitro‐containing esters (2, 3) in very good yields. Compounds 2 and 3 were also isolated in similar yields by the treatment of 1 with oxalic acid or malonic acid in trifluoroacetic anhydride at room temperature. Nitration of 3 with fuming nitric acid resulted
