Enantioselective Ullmann Ether Couplings: Syntheses of (鈭?-Myricatomentogenin, (鈭?-Jugcathanin, (+)-Galeon, and (+)-Pterocarine
文摘
The first enantioselective Ullmann cross-coupling reactions to prepare diaryl ethers are reported. The reactions were used to prepare the diarylether heptanoid natural products (鈭?-myricatomentogenin, (鈭?-jugcathanin, (+)-galeon, and (+)-pterocarine.
