3, 1-benzoxazines, N-(2-cyclopent-1-en-1-ylphenyl)benzamides, mass spectra of 2-arylspiro-[3, 1-benzoxazin-4, 1'-cyclopentanes] and N-(2-cyclopentenyl)benzamides, cyclizationAbstract
The cyclization has been studied of N-(2-cyclopent-1-en-1-ylphenyl)benzamides into the corresponding 3,1-benzoxazines by the action of gaseous hydrogen chloride, trifluoroacetic acid, or bromine, and also under conditions of electron impact in the gas phase. A scheme is proposed for the fragmentation of the molecular ions of the products obtained.
