Chirality in Diarylether Heptanoids: Synthesis of Myricatomentogenin, Jugcathanin, and Congeners
摘要:
The syntheses of myricatomentogenin, jugcathanin, galeon, pterocarine, and acerogenin L are reported. Synthetic material was used to measure their optical activities and free energy of activation for racemization. The natural enantiomers of myricatomentogenin, jugcathanin, galeon, and pterocarine were determined to have the same pR absolute stereochemistry. Acerogenins L and C are achlral compounds.

The first enantioselective Ullmann cross-coupling reactions to prepare diaryl ethers are reported. The reactions were used to prepare the diarylether heptanoid natural products (-)-myricatomentogenin, (-)-jugcathanin, (+)-galeon, and (+)-pterocarine.
