pure 3-o-fluorobenzyloxy-2-hydroxy-2'-(p-methoxybemzyl)-1,1'-binaphthyl.SnCl4, which is effective for the enantioselective cyclization of 2-(polyprenyl)phenol derivatives to afford polycyclic terpenoids bearing a chroman skeleton such as (-)-chromazonarol, (+)-8-epi-puupehedione, a key synthetic intermediate of (+)-wiedendiol, and (-)-11'-deoxytaondiol methyl ether.
本文介绍了一种新型人工环化酶,光学纯的 3-o-fluorobenzyloxy-2-hydroxy-2'-(p-methoxybemzyl)-1,1'-binaphthyl.SnCl4,可有效地对映选择性环化 2-(polyprenyl ) 苯酚衍生物,提供带有色满骨架的多环萜类化合物,例如 (-)-chromazonarol、(+)-8-epi-puupehedione、(+)-wiedendiol 的关键合成中间体和 (-)-11'-deoxytaondiolmethyl醚。
