✦ Synopsis

Title azaannulenes were synthesized starting from annulenones, and the rH-NMR spectra are discussed in connection with tropicity of these annulenes.

The synthesis of monoazaannulenes, the higher homologues of pyridine, remains one of the stimulating problem in the study of nonbenzenoid aromatic system.
