An efficient and rapid synthesis of furo[3,2-b]pyridine 1 is described using a one-pot Sonogashira coupling/heteroannulation sequence. Regioselectivelithiation of this synthon was performed leading to various 2-substituted furo[3,2-b]pyridines. Some of them were used as substrates for short functional synthesis of polyheterocycles.

The present invention relates to compounds of formula (I) that are inhibitors of PlKfyve kinase and are therefore useful for the treatment of e.g. neurological diseases, such as e.g. amyotrophic lateral sclerosis (ALS), Parkinson's disease, Alzheimer's disease, Huntington's disease, ADHD, schizophrenia, depression, or bipolar disorder. An exemplary compound is e.g. 7-morpholino-5-(3-phenyl-lH- pyrazol-l-yl)-2-(lH-pyrazol-4-yl)furo[3, 2-b]pyridine (compound 10) Data on the PlKfyve kinase inhibition are provided, e.g.:
Copper Pincer Complexes as Advantageous Catalysts for the Heteroannulation of<i>ortho</i>-Halophenols and Alkynes
A new, non‐symmetrical copper(II) pincercomplex catalyzes much more efficiently the formation of benzofuran by the reaction between ortho‐iodophenols and alkynes. The lowest catalyst loadings are realized for this reaction, and bromo‐ and chlorophenols are heteroannulated for the first time. Strong evidence for hydrophenoxylation and intramolecular halogen atom‐transfer steps catalyzed by this remarkably
