protocol for the synthesis of the tertiary hydroxyl natural-like thieno[2,3-d]pyrimidinone skeleton was developed from the cyclocondensation of o-aminothienonitrile and carbonyl compound. The reaction process includes PDF conversion and photo-catalytic oxygenation. This synthetic strategy offers an alternative method for regioselective construction of tertiary hydroxylated thieno[2,3-d]pyrimidinone architectures

A series of new thienopyrimidinone derivatives were synthesized via a novel, straightforward and efficient tandem cyclo condensation of o-aminothienonitrile 1 and carbonyl compounds 2 in different conditions. The synthesized four thienopyrimidinone skeletons were thieno[2,3-d]pyrimidinone 3, tert-hydroxythieno[2,3-d]pyrimidinone 4, symmetrical tetracycle thienothiophene-pyrimidone 5 and thienopyrimidine 6 respectively. Their plausible mechanisms were proposed. The properties of compound 5 were investigated.
Solvent-Free synthesis of 2-Aminothiophene-3-Carbonitrile Derivatives Using High-Speed Vibration Milling
The solvent-free synthesis of 2-aminothiophene-3-carbonitrile derivatives by high-speed vibration milling using the inexpensive and environmentally friendly Et2NH as a catalyst was studied. The reaction conditions were optimised and the derivatives were obtained in good yield. This method has advantages in terms of short reaction time and facile conditions.
