A small molecular model compound for the green fluorescent proteinchromophore was readily synthesized by a novel condensation reaction of (thio)imidate with imino-ester via an aziridine intermediate. This compound showed fluorescence in the solid and frozen solution states but not in the solution state. Its fluorescent property was successfully applied in the detection of dsDNA.

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 acetyl chloride N-acetyl derivatives were obtained as by- or sole products.
