Efficient synthesis of halohydroxypyridines by hydroxydeboronation
摘要:
This paper describes a general method for the synthesis of halohydroxypyridines from novel halopyridinylboronic acids and esters recently described by some of us. Halopyridinylboronic acids and esters have been efficiently hydroxydeboronated under mild conditions by employing hydrogen peroxide or meta-chloroperbenzoic acid. These hydroxylations take place regioselectively, without other oxidation (N-oxide formation). (C) 2004 Elsevier Ltd. All rights reserved.

This letter describes the development of a series of potent and selective small molecule Legumain inhibitors suitable as chemical probes for in vitro experiments. Our previous research had identified a dipeptide inhibitor utilizing a semi-reversible cyano warhead that generated 2, a cell active inhibitor. This work explores an alternative P2-P3 linker and further SAR exploration of the P3 group which

Parkinson’sdisease (PD) is a progressive neurodegenerative disorder that affects movement. The nonreceptor tyrosine kinase c-Abl has shown a potential role in the progression of PD. As such, c-Abl inhibition is a promising candidate for neuroprotection in PD and α-synucleinopathies. Compound5 is a newly synthesized blood–brain barrier penetrant c-Ablinhibitor with higher efficacy than existing inhibitors
