  The synthetic versatility of alkoxycarbonyl- and hydroxymethyl-piperazine-2,5-diones

  摘要：

  Alkoxycarbonylpiperazine-2,5-diones are versatile precursors for the alpha-functionalisation of piperazine-2,5-diones. The alkoxycarbonyl group activates the a-carbon position to alkylation reactions and this provides a mild and selective method for the extension of the carbon framework of piperazine-2,5-diones. In addition, the alkoxycarbonyl group can be converted to the carboxy group, which in turn can be 'deleted' or manipulated for the installation of carbon and/or heteroatom substituents where desired, the latter via N-acyliminium chemistry. We also demonstrate that hydroxymethylpiperazine-2,5-diones complement carboxypiperazinediones as precursors for the generation of N-acyliminium ions. (c) 2005 Elsevier Ltd. All-rights reserved.

  The asymmetric organocatalytic alpha-sulfenylation of substituted piperazine-2,5-diones is reported, with cinchona alkaloids as chiral Lewis bases and electrophilic sulfur transfer reagents. Catalyst loadings, the type of sulfur transfer reagent, temperature and solvent were investigated in order to optimize the reaction conditions. The effects of ring substitution and the type of catalyst on the yield and enantioselectivity of the reaction are reported. (C) 2009 Elsevier Ltd. All rights reserved.

  Organocatalytic alpha-sulfenylation of substituted piperazine-2,5-diones is reported through the use of cinchona alkaloids as Lewis bases and electrophilic sulfur transfer reagents. 1-Phenylsulfanyl[1,2,4]triazole, a novel Sulfur transfer reagent, gave excellent product yields with a number of substituted piperazine-2,5-diones under mild conditions. Catalyst loading, stoichiometry Of Sulfur electrophile, temperature, and solvent were optimized to achieve high product yields. (C) 2009 Elsevier Ltd. All rights reserved.
