Tetrahydroquinazoline Derivatives by Aza Diels-Alder Reaction
摘要:
The reaction of N-(2-Chloromethylphenyl)benzenesulfonamides (1) with N-benzylideneamines (2) gives 1,2,3,4-tetrahydroquinazoline derivatives (3) via the highly reactive o-azaxylylene intermediates. The structure of (3) is fully assigned on the basis of analytical and spectroscopic data. The chemical behaviour of (3) has been studied.
