A general synthesis for the preparation of a series of N-bridgehead compounds: pyrroloimidazopyridine, pyrimidine and naphthyridine has been developed beginning with azidovinyl compounds with thermolytic or photochemical methods
Different routes of formation of aza-γ-carboline ring-system are discussed. In addition the reactivity of an aminoderivative in comparison with an iminophosphorane compound is investigated.
