The present invention relates to N-(hetero)aryl-pyrrolidine derivatives of Formula I:
which are JAK inhibitors, such as selective JAK1 inhibitors, useful in the treatment of JAK-associated diseases including, for example, inflammatory and autoimmune disorders, as well as cancer.
A method for the oxidativenitration of alkenes using a combination of tert-butyl nitrite and molecular oxygen to give β-nitro alcohols and their nitrate derivatives has been developed. The present reaction provides a practical method for the synthesis of nitro compounds because of the mild reaction conditions, the use of inexpensive reagents and a simple experimental procedure.
