Synthesis of Imidazoles from Alkenes

Casey, Michael,Moody, Christopher J.,Rees, Charles W.

, p. 1933 - 1941 (2007/10/02)

Alkenes are converted into imidazoles through their epoxides by a sequence involving ring-opening with readily available 2-tributylstannyltetrazoles (8), dehydration of the resulting alcohols (9) using methyltriphenoxyphosphonium iodide in a improved procedure to give 1-alkenyltetrazoles (12), which give imidazoles (17) on photolysis.
