The dehydrovaline acrylamide (3) has been photolysed to yield the novel fused β-lactamsystem (4); this finding opens up a possible route to compounds which may be of interest in the light of current views on the mode of action of β-lactam antibiotics.

The photochemistry of a series of β-thioacrylamides has been investigated. The acyclic compounds (9)–(12) undergo cis–trans isomerisation and cyclisation to oxazoles such as (13) and (21). The cyclic β-thioacrylamide (23) undergoes a π2s+π2s cycloaddition reaction to give the interesting tricyclic β-lactam (29).
