Various alkylarenes were successfully transformed into the corresponding 2‐amino‐4‐arylthiazoles and 2,4‐diarylthiazoles in good to moderate yields by the treatment with NBS, followed by the reaction with thioureas or arenethioamides.

This invention relates to the use of thiazolopyrimidinone derivatives for the modulation, notably the inhibition of the activity or function of the phosphoinositide 3' OH kinase family (hereinafter PI3 kinases), suitably, PI3Kα, PI3Kδ, PI3Kβ, and/or PI3Kγ. Suitably, the present invention relates to the use of thiazolopyrimidinones in the treatment of one or more disease states selected from: autoimmune disorders, inflammatory diseases, cardiovascular diseases, neurodegenerative diseases, allergy, asthma, pancreatitis, multiorgan failure, kidney diseases, platelet aggregation, cancer, sperm motility, transplantation rejection, graft rejection and lung injuries. More suitably, the present invention relates to PI3Kβ selective thiazolopyrimidinones compounds for treating cancer.

method for copper-catalyzed benzylic C–Halkynylation that uses alkynylboronic esters as nucleophilic coupling partners. The catalytic system is readily available and the reaction takes place under mild conditions. Different substrates for the C–H functionalization, as well as various alkynylboronic ester nucleophiles, were evaluated. Finally, three examples of enantioselective C–Halkynylations are presented
A catalytic dearomative three-componentreaction of bromoarenes with TMS-diazomethane and allyl borate was developed. The key of this assembling reaction is the use of a diazocompound to generate a Pd-π-benzyl intermediate through a Pd-carbene species. This method allowed for a dearomative functionalization, using arenes as limiting reagents. Heteroaryl bromides were also applicable to give dearomatized
