The present invention provides compounds of Formula (I) or a pharmaceutically acceptable salt thereof; (I) which are inhibitors of WDR5. The present invention also provides pharmaceutical compositions comprising such compounds, compositions comprising such compounds with an additional therapeutic agent and the therapeutic uses of such compounds.
[reaction: see text] N-Methyl-4-alkoxy-3-alkynylpyridin-2(1H)-ones readily undergo iodine-promoted 5-endo-heteroannulation under mild conditions to 3-iodofuropyridinium triiodide salts in moderate to good yields. The latter may be dealkylated in situ upon exposure to an iodide anion to provide the corresponding 3-iodofuro[2,3-b]pyridin-4(1H)-ones. The same strategy applies to the formation of furo[2
[reaction: see text] The one-pot assembly of 4-alkoxy-3-iodo-2-pyridones, terminal alkynes, and organic halides has been achieved by integration of two sequential palladium-mediated cross-coupling reactions--Sonogashira and Wacker-type heteroannulation processes--and subsequent deprotection of the alkoxy group to afford furo[2,3-b]pyridones.
The present invention provides a heterocyclic compound having a HDAC inhibitory action, which is useful for the treatment of central nervous system diseases including neurodegenerative diseases, and the like, and a medicament comprising the compound.
The present invention relates to a compound represented by the formula (I):
wherein each symbol is as described in the description, or a salt thereof.
