  Conjugate-addition reactions of .alpha.-sulfinyl ketimine anions with a methyl .alpha.-amidoacrylate. Concise asymmetric total syntheses of (-)-slaframine and (-)-6-epislaframine

  摘要：

  The in-situ 1,4-addition/ring-closure reactions of chiral alpha-sulfinyl ketimine anions with a methyl alpha-amidoacrylate provide a simple method for the construction of optically pure 6-aminoindolizidinones. This method afforded the syntheses of (-)-slaframine and (-)-6-epislaframine in six steps, respectively, from (+/-)-3-[(tert-butyldimethylsilyl)oxy]-4,5-dihydro-2-methyl-3H-pyrrole (9). Stereoselective reductions of alpha-sulfinyl ketimines (such as 10) were also developed.
