摘要: Tropone 2a and tropolone methyl ether 2b react with nitrilium salts (1a-j) to give the bicyclic oxazolium 3, 5. Cleavage of N–C3a bond 5 followed by y Chapman rearrangement afford stable N-acyliminium 4, 8. A crystal structure analysis for 3a is reported. AM1 calculations are in accord proposed mechanisms formation
