Abstract
Several optically active azetidinethiones were obtained from
the corresponding ~-lactams by reaction with Lawesson's reagent.
The same Cotton effect sign in the n-n* region shown by B-lactones
and their thioxo analogues points to the similar nature of long-wavelength electronic transitions of both classes of compounds.
