Synthesis of isochromene pyrimidinedione derivatives having five stereocenters has been achieved by a one-pot Michael-Knoevenagel condensation-inverse-electron-demand hetero-Diels-Alder reaction of α, β-unsaturated aldehydes, olefinic nitroalkanes, and 1,3-dimethylbarbituric acid via a one-pot strategy with excellent diastereo- and enantioselectivities (up to 99% ee).

Unique three-component self-assembly of a cis-blocked 90° Pd(II) acceptor with a mixture of tri- and tetra-imidazole donors led to the self-sorting of a Pd7 molecular boat with an internal nanocavity, which catalyses the Knoevenagel condensation of a series of aromatic

Microwave assisted indirect functionalization of alcohols with 1,3-dimethylbarbituric acid followed by spirocyclisation employing a sequential one-pot Ir(III)/Pd(0) catalysed process, involving the formation of three new C-C bonds, one spirocyclic ring and one di- or tri-substituted exocyclic alkene, is described.

Electrochemical oxidation of trimipramine in the absence and presence of 1,3 dimethyl barbituric acid as a nucleophile in aqueous solution has been studied using cyclic voltammetry and controlled-potential coulometry electrolysis. Voltammetric studies of electro-oxidation of trimipramine were realized in a
