## Abstract Aziridine‐2‐carboxylic esters 1 were converted into 2__H__‐azirine‐2‐carboxylic esters 4 in two steps. Treatment of 1 with __tert__‐butyl hypochlorite in ether gave smooth __N__‐chlorination. Reaction of __N__‐chloroaziridines 2 with 1,8‐diazabicyclo[5.4.0]undec‐7‐ene (DBU) or 1,4‐diaza

tert-Butyldimethylsililoxy-2-aza-1,3-butadienes react with 2H-azirine 3 leading to Diels-Alder cycloadducts in moderate yields. The reactions are endo-and regioselective with the azirine being added by its less hindered face. There is only one product in the case of 1b, 4b. There are two isomers (4
