1,3-Dimethylbarbituric acid (C007B-108940)

1,3-Dimethylbarbituric acid (1,3-Dimethyl-2,4,6(1H,3H,5H)-pyrimidinetrione) is an active methylene compound. It undergoes hollow Pd6 water-soluble cage, [{(tmen)Pd}6(timb)4](NO3)12 (tmen= N,N,N′,N′-tetramethylethylenediamine, timb=1,3,5-tris(1-imidazolyl)benzene)-catalyzed Knoevenagel condensation reaction with pyrene-1-carboxaldehyde.It undergoes self-sorted Pd7 molecular boat having an internal nanocavity (catalyst)-assisted Knoevenagel condensation reaction with various aromatic aldehydes. It has been synthesized by reacting 1,3-dimethylurea, malonic acid and acetic anhydride in acetic acid. It is widely used for the synthesis of various synthetic intermediates and heterocyclic compounds Usually used in the following studies: Enantioselective synthesis of isochromene pyrimidinedione derivatives having five stereocenters, via one-pot Michael-Knoevenagel condensation-inverse-electron-demand hetero-Diels-Alder reaction;Synthesis of 5-aryl-6-(alkyl- or aryl-amino)-1,3-dimethylfuro [2,3-d]pyrimidine derivatives; Microwave promoted indirect functionalization of alcohols, via spirocyclisation employing a sequential one-pot Ir(III)/Pd(0) catalyzed process.
