Multi-step in flow: The palladium-catalysed acylation of terminal alkynes for the synthesis of yne[BOND]ones as well as their further transformation to various heterocycles in a continuous-flow mode is presented. Furthermore, an extension of the simple flow configuration that allows for easy batch splitting and the generation of a heterocyclic library is described (see scheme).
