1,3-dipolar cycloaddition reactions to gal-anthamine nitrone:an entry to 4a,5,9,10-tetra-hydro-6h,14ah-benzofuro3a,3,2-efisoxazolo3,2-a-2benzazepines

摘要

Starting with galanthamine nitrone as the 1,3-dipole derivatives of the novel 4a,5,9,10-tetrahydro-6H,14a/f-benzofuro3a,3,2-efisoxazolo3,2-a2-benzazepine ring system have been prepared by cycloaddition.
