The present invention is related to novel pyrimidinedione-fused heterocyclic compounds as TRPA (Transient Receptor Potential subfamily A) modulators. In particular, compounds described herein are useful for treating or preventing diseases, conditions and/or disorders modulated by TRPA1 (Transient Receptor Potential subfamily A, member 1). Also provided herein are processes for preparing compounds described herein, intermediates used in their synthesis, pharmaceutical compositions thereof, and methods for treating or preventing diseases, conditions and/or disorders modulated by TRPA1.
The synthesis of pyrimidineisothiazolones. The effect of temperature on the addition of aryl amines to functionalized pyrimidines

A new synthesis for the hither-to-unknown pyrimidine isothiazolones 1 and 2 is detailed. The low temperature selectivity of amine nucleophiles on 6-chloropyrimidine-5-acylbromides (12) for the acylbromide over the ring chloride provides a new procedure fo

, p. 342 - 344 (2007/10/02)
1,3-Dimethyluracils having a nitrile oxide moiety or a nitronomethyl group at C-5 and an N-aryl-2-thienylmethylamino group at C-6 undergo an intramolecular cycloaddition reaction to give novel uracil-fused heterocycles.
Studies of Pyrimidine-2,4-diones: Synthesis of Novel Condensed Pyridopyrimidines via Intramolecular Cycloadditions
Prajapati, Dipak,Bhuyan, Pulakjyoti,Sandhu, Jagir Singh
, p. 607 - 610 (2007/10/02)
Suitably functionalised pyrimidine-2,4-diones (1) cyclised intramolecularly to yield the novel furoisoxazolopyridopyrimidines (5) and (9) in excellent yields.Remarkably, the pyrimidone nucleus was unaffected nor were there any side-reactions in this synthesis.
