Conformational analysis of 2,3-dihydro-2,2-dimethyl-1,4-benzoxazepines and their 1,5-isomers
摘要:
Conformational analysis of 2,3-dihydro-2,2-dimethyl-1,4-benzoxazepines (1, 3, 5, and 7) and their 1,5-isomers (2, ii, and 6) was performed by temperature dependent NMR measurements. The effect of substituents on the ring inversion was studied. The results obtained were corroborated by AMl calculations.
