NEW HETEROCYCLIC SYSTEMATIC SYNTHESIS V.THE SYNTHESIS AND CHARACTERISTICS OF 1,3a,5-TRISUBSTITUTED-3a,4,5,11-TETRAHYDRO-1,2,4-OXADIAZOLINO[5,4-d][1,5]BENZODIHETEROPINES
NEW HETEROCYCLIC SYSTEMATIC SYNTHESIS V.THE SYNTHESIS AND CHARACTERISTICS OF 1,3a,5-TRISUBSTITUTED-3a,4,5,11-TETRAHYDRO-1,2,4-OXADIAZOLINO[5,4-d][1,5]BENZODIHETEROPINES
摘要
Twenty-seven oxadiazolino[5,4-d][1,5]benzodiheteropine derivatives have been synthesized by the 1,3-dipolar cycloaddition of benzodiheteropines with nitrile oxide 1,3-dipoles,their conformations and the characteristics of the newly formed oxadiazoline fused on them have been studied.It has also been found that the mass spectra show characteristic fragmentation patterns.
