β-lactams, including a cepham analog, were synthesized by the photochemical reaction of [(methoxy)(methyl)carbene]chromiumcomplexes with substituted imines. Oxazines and oxazolines were inert towards chromiumcarbenecomplexes. Oxazines were converted to bicyclic β-lactams by the photolyticreaction of molybdenum carbenecomplexes. Oxazolines were considerably less reactive and produced only low yields
