1,3-DIPOLAR CYCLOADDITION OF NITRILE OXIDES TO 8-AZAHEPTAFULVENES
Gandolfi, Remo,Gamba, Anna,Gruenanger, Paolo
, p. 619 - 638 (1995)
Azaheptafulvenes (2) reacted readily with nitrile oxides (1) to give, as a rule, only adducts derived from a reaction involving the C=N moiety of 2.The adducts consisted of a mixture of rapidly equilibrating "spiro" and "condensed" isomers, i.e. 68, wh
1,3-DIPOLAR CYCLOADDITION REACTIONS OF N-ARYL-2,4,6-CYCLOHEPTATRIEN-1-IMINES WITH p-SUBSTITUTED BENZONITRILE OXIDES: FORMATIONS OF 1,2,4-OXADIAZASPIROUNDECA-6,8,10-TRIENES

Reactions of N-aryl-2,4,6-cycloheptatrien-1-imines with p-substituted benzonitrile oxides afforded 1,2,4-oxadiazaspiroundeca-6,8,10-trienes via type cycloadditions.The study of substituent effects on the reaction rates suggested the nucleophili
