It was found that dialkyl(4-hydroxybut-2-ynyl)methallyl- and dialkylcrotyl(4-hydroxybut-2-ynyl)- ammonium halides undergo a Stevens rearrangement under the influence of aqueous alkali with transfer of the reaction center in the receiving group and inversion of the migrating group followed by cyclization to amino derivatives of furan.
