and its reactivity as electrophilic cyanation reagent evaluated. The scalable preparation, easy handling and broad substrate scope of the electrophilic cyanation promoted by 9, which includes amines, thiols, silyl enol ethers, alkenes, electron rich (hetero)arenes and polyaromatic hydrocarbons, illustrate the synthetic potential of this reagent. Importantly, Lewis acid activation of the reagent is not
The present invention relates to thiopyrimidine-based compounds that are inhibitors of protein kinases including JAK kinases. In particular, the compounds are selective for JAK1, JAK2 or JAK3 kinases and combinations thereof such as JAK1 and JAK2. The kinase inhibitors can be used in the treatment of kinase associated diseases such as immunological and inflammatory diseases including organ transplants; hyperproliferative diseases including cancer and myeloproliferative diseases; viral diseases; metabolic diseases and vascular diseases.
