alkenes and alcohols/thiols mediated by boron trifluoride etherate leads to five-membered thiazolidine, six-membered 1,4-oxazines (morpholines) and tetrahydro-2H-1,4-thiazines (thiomorpholines), and seven-membered 1,4-oxazepanes in good yields.
三氟化硼醚化物介导的氮链烯烃和醇/硫醇的分子内加氢烷氧基化/氢硫代烷氧基化反应会生成五元噻唑烷,六元1,4-恶嗪(吗啉)和四氢-2 H -1,4-噻嗪(硫吗啉) ,和七元1,4-恶唑烷,收率高。
