utilizing a Pd-catalyzed equilibration of diastereomeric 5-vinyloxazolines to set the stereochemistry of the vicinal amino and hydroxyl groups. A ruthenium-catalyzed ring-closing metathesis was employed to form the seven-membered nitrogen heterocyle.
一种有效的蛋白激酶C抑制剂balanol的对映选择性形式合成,是通过D-丝氨酸利用Pd催化的非对映体5-乙烯基恶唑啉的平衡来设定邻位氨基和羟基的立体化学而完成的。钌催化的闭环复分解被用来形成七元氮杂环。
