## Abstract Starting from methylthioimidates 1–8 a series of corresponding tricyclic β‐lactams was synthesized __via__ [2+2]cycloaddition with ketenes generated __in situ__ from substituted acetyl chlorides. Dependent on the bicyclic starting material and on the substituent of the corresponding ace
