Propargylic esters undergo the Claisen ester rearrangement to give allenyl acetic acids which thermally decarboxylate to give substituted buta-1,3-dienes.

Amine-Release Annulation of Enaminones: Bimetallic Co-Catalytic Synthesis of Cyclopentadienes from Alkynes
An efficientAu(III)/Ag(I) co-catalytic platform has been established for the synthesis of cyclopentadienes through amine-release annulation of enaminones with alkynes. Vinylcarbenoids that were generated from 1,2-migration of propargyl esters may undergo a tandem annulation process with enaminones to give aminocyclopentenes as key intermediates. The bimetal catalytic system is compatible with a broad
