Abstract The precursor, piperazine-1, 4-diylbis (2-oxoethane-2, 1-diyl) bis (4-
formylbenzoate) was prepared by reacting 1, 1'-(piperazine-1, 4-diyl) bis (2-chloroethan-1 …

In this work, we have developed green and efficient regioselective and chemoselective
syntheses of 5‐aryloyl‐1, 3‐dimethyl‐7‐thioxo‐5, 6, 7, 8‐tetrahydropyrimido [4, 5‐d] …

A synthesis of novel bis (tetrahydropyrimido [4, 5-b] quinoline-4, 6-diones) connected to
butenyl and butynyl spacers via thioether linkages is reported. Two equivalents of the …
