“…The structure of 112) was also confirmed by its catalytic hydrogenation to the known saturated derivative 12 [4]. [2] it can be concluded that in going from carbocyclic to analogous heterocyclic systems the nature of the heteroatoms may play an important role in the photochemical behaviour of the different compounds. Thus, in the case of lactam 6 the influence of the enamide function predominates over the one of the d'*s(6)-unsaturated system, so that 6 undergoes photo-oxidation phenomena, which may be considered typical [4] of that chromophore, rather than a di-71-methane rearrangement as in the case of the enol- …”
