Given are experimental data indicating that base-catalyzed intramolecular cyclization of ammonium salts containing a 2-propynyl-like group together with a 3-alkenyl- or 3-aryl-2-propynyl group follows a concerted mechanism involving the 3-alkenyl- or 3-aryl-2-propynyl moiety as π4-fragment.
Base-catalysed rearrangement of allyl-propynyl ammonium cations in protic media
Laird,Ollis
, p. 557 - 559 (1972)
The base-catalysed rearrangement of the allylpropynyl ammonium cations (I) in aqueous solution yields either the isomeric cations (II) or the aldehydes (III) and (IV), or mixtures of (II), (III), and (IV); this result contrasts dramatically with the trans
