By using a combination of a chiral N‐triflyl phosphoramide and TiCl4 as the catalyst, a new process for asymmetric intramolecular hydroalkoxylation of unactivated alkenes was developed, producing various chiral tetrahydrofuran derivatives in 51%—99% yields with 30%—71% ee's.
通过使用手性N- triflyl磷酰胺和TiCl 4的组合,开发了一种新的未活化烯烃不对称分子内氢烷氧基化的新工艺,以51%-99%的收率和30%-71%ee的产率生产了各种手性四氢呋喃衍生物。 。
