Notes:
It is shown that LiAIH4 reduces cyclic imides, namely 3,3-disubstituted 2,5-dioxo-pyrrolidines and 2,6-dioxo-piperidines, primarily at the oxo-group not adjacent to the two substituents. Hydroxylactames are formed as the first reduction products. Similarly, the same oxygen atom is replaced by sulfur by reaction with P2S5. This behaviour is ascribed to steric hindrance.
