Enamines are versatile compounds capable of alkylations, acylations, cycloadditions
and annulation cascades. They are also involved in a range of heterocycle-forming processes.1,2 The broad applicability of heterocyclic secondary enamines in synthesis has
been amply demonstrated in the past two decades.3,4 The reaction conditions, yield and
nature of enamine ring-opening have received great attention in the literature.
