Novel method for construction of tetrahydro-1-benzazepine and tetrahydro-2-benzazepine based on 7-endo selective Friedel–Crafts cyclization of vinyloxirane
-
Add time:08/17/2019 Source:sciencedirect.com
The 7-endo Friedel–Crafts cyclization of vinyloxiranes, which have a nitrogen atom at the linker between the aromatic ring and the epoxide, was found to proceed regio- and stereoselectively to afford polyfunctional tetrahydro-1-benzazepine and tetrahydro-2-benzazepine.
