We describe the photoinduced addition of methanol to 5(S)-5- triisopropylsiloxymethyl-N-boc-dihydropyrrole-2(5H)-one to produce 5(S)-5- triisopropylsiloxymethyl-4(S)-hydroxymethyl-pyrrolidine-2-one, and conversion of this into a variety of 4(S), 5(S)-pyrrolidine-2-ones. Photo-induced addition of methanol to 5(R)-N-boc-5-amino-dihydropyran-2(5H)-one yielded the unexpected product 4(S)-1'-[2'-hydroxy, 1'-(R)-N-boc-amino]ethyl- tetrahydrofuran-2-one via rearrangement of the initial photoadduct.
