  A general approach to polysubstituted pyrroles

  摘要：

  Exposure of a range of 3-hydroxy-2-sulfonylamino-4-alkynes to excess iodine delivers good yields of a series of iodopyrroles. Unexpectedly, the hydroxyl-dihydropyrroles, which were assumed to be the first-formed intermediates, turn out to be stable entities which have been isolated for the first time. (C) 2007 Elsevier Ltd.

  Enantioselective Synthesis of anti-β-Hydroxy-α-amido Esters via Transfer Hydrogenation

  摘要：

  The asymmetric transfer hydrogenation of alpha-amido-beta-keto esters to provide the corresponding anti-beta-hydroxy-alpha-amido esters in good to excellent yields, diastereoselectivity, and enantioselectivity is reported. The procedure is operationally simple, and delicate handling of the catalyst is not necessary.

  In situ generated osmium-diamine chelates from 2,3-diaminopropionic acid or diaminosuccinic acid represent efficient catalysts for the highly productive aminohydroxylation of alkenes. The reaction can be employed with various osmium salts and successful catalyst recycling was demonstrated for a representative example. The catalyst design derives from the general structural features of recently investigated
