P. Somfai et J. Ahman, A QUALITATIVE INVESTIGATION OF SUBSTITUENT EFFECTS IN THE HOMODIENYL-[1,5]-HYDROGEN SHIFT IN VINYLAZIRIDINES, Tetrahedron letters, 36(11), 1995, pp. 1953-1956
The homodienyl-[1,5]-hydrogen shift in vinylaziridines 4a-h has been i
nvestigated. It has been found that substituents capable of conjugatio
n at the rearrangement origin will reduce the reaction time while subs
tituents on the vinyl moiety affect the rate most notably when they ar
e capable of interfering sterically with he other ring substituents.
