intermediates, which are in the correct oxidation state to undergo a base-induced elimination to reveal the aromatic 2-pyridone. This mild and novel approach to six-memberedheteroaromatic compounds then provides access to a wide variety of substituted pyridines in excellent overall yield.

Ring-closing olefin metathesis (RCM) has been applied to the efficient synthesis of densely and diversely substituted pyridine and pyridazine frameworks. Routes to suitable metathesis precursors have been investigated and the scope of the metathesis step has been probed. The metathesis products function as precursors to the target heteroaromatic structures via elimination of a suitable leaving group, which
The present technology is directed to compounds, compositions, and methods related to modulation of MNK. In particular, the present compounds and compositions may be used to treat MNK-mediated disorders and conditions, including, e.g., various solid and hematological cancers.
Provided is a polycyclic compound inhibiting MNK1 and MNK2. Specifically, provided is a compound represented by formula (I), or stereoisomers, tautomers, or pharmaceutically acceptable salts thereof, wherein the definition of each group is as described in the description. These compounds can be used for preparing pharmaceutical compositions for the treatment of diseases or disorders related to MNK activity or expression level.
