  Photoinduced addition of methanol to 5(S)-5-triisopropylsiloxymethyl-N-boc-dihydropyrrole-2(5H)-one: A new route to 4(S), 5(S)-disubstituted pyrrolidin-2-ones

  摘要：

  We describe the photoinduced addition of methanol to 5(S)-5-triisopropylsiloxymethyl-N-boc-dihydropyrrole-2(5H)-one to produce 5(S)-triisopropylsiloxymethyl-4( S)-hydroxymethylpyrrolidine-2-one, and conversion of this into a variety of 4( S), S(S)-pyrrolidine-2-ones. Photoinduced 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.

  A unified synthetic strategy toward oroidin-derived alkaloids premised on a biosynthetic proposal

  摘要：

  Details of the evolution of a synthetic strategy toward the spirocyclic chlorocyclopentane core of oroidin-derived alkaloids, including the axinellamines and potentially adaptable to palau'amine, are described. A proposed refinement of the Kinnel-Scheuer biosynthetic proposal for palau'amine is posited. Studies undertaken to improve the regioselectivity and efficiency of a key Diels-Alder reaction utilizing a novel protecting group strategy, microwave chemistry, and other strategies are described. Further insights regarding the suitability of different protecting groups during the epoxidation/chlorination/ring contraction sequence are disclosed. Several interesting by-products from this reaction sequence are reported. These studies have led to a unified synthetic strategy to the axinellamines and palau'amine. (c) 2006 Elsevier Ltd.
