  Total Synthesis and Absolute Configuration of Riccardiphenols A and B, Isolated from the Liverwort Riccardia crassa

  摘要：

  The title compounds were synthesized as optically active forms using chiral Michael addition of the imine, prepared from 2-methylcyclohexanone and (S)-(-)-phenylethylamine, to methyl propiolate. The etherification of the intermediate triol was accomplished by TsOH-catalyzed cyclization. The absolute configurations of the natural products, riccardiphenols A and B, were established as 1 and 2, respectively.
