The present invention provides substituted bicyclic heteroaryl compounds, 5 including, for example, 4-pyrazoIyI-N-arylpyrirnidin-2-arnines and 4-pyrazolyl-N-heteroarylpyτimidin-2-amines that modulate the activity of kinases and are useful in the treatment of diseases related to activity of kinases including, for example, immune-related diseases, skin disorders, myeloid proliferative disorders, cancer, and other diseases.formule :(1)
polycyclic carbamyl pyridone analogues of Baloxavir marboxil from the cyclization of chloroacetaldehyde with o-aminoamide derivatives. In this method, without any other catalysts or additives, the polycyclic carbamoyl pyridone analogues can be obtained by ring closure of o-aminoamide derivatives and chloroacetaldehyde under the action of a base, and no harsh reaction conditions are required.

transformations are based on the fact that DMF can serve as a reaction solvent and one carbon synthon for the construction of heterocyclic rings. Moreover, this protocol features base-free and Brønsted acid free environmentally benign conditions with broad synthetic scope. A good scalability is demonstrated.
