“…2). Likewise the corresponding alkyenes substrates can be readily accessed at industrial scale from simple dehydrogenation of the corresponding styrene or alkane precursors [23][24][25][26][27][28][29][30] which although currently are most often sourced from petrochemical feedstock are increasingly being derived from bio-feeds. [31][32][33] Such consideration gives additional merit to a future production route originating from these starting materials.…”

Current batch procedures to synthesise coumalic acid have several drawbacks, which we address with the aid of tubular flow systems and a simple heated rotating flow reactor. The prepared coumalate derivatives can be further used in inverse electron demand Diels-Alder reactions to synthesise compounds with many applications including molecular electronics, with the added advantage of providing metal-free preparations. Historical context: syntheses of coumalic acid and derivativesThe earliest documented synthesis of coumalic acid was published by von Pechmann in 1891 starting from malic acid. 14 A mixture of concentrated sulfuric acid (97-98%) and fuming sulfuric acid was used at 70 °C to effect conversion to coumalic acid, in a reported 70% yield. Caldwell et al. reproduced the a.
