Banert cascade
The Banert cascade is an
dioxane- water mixture at elevated temperatures.[1] It is named after Klaus Banert, who first reported the process in 1989.[2] This cascade reaction is unusual because it consists of two consecutive rearrangement reactions
.
The starting material is prepared from
dipole moment of 5 debye. The reaction sequence concludes with nucleophilic attack
of a second azide ion on this alkene with more double bond rearrangements and proton abstraction from a proton source.
