Conjugateaddition of α,β-unsaturated ketones with arylzinc species that form in situ from diethylzinc and a series of arylboronic acids by boron-zinc exchange reactions were investigated. 1,4-Addition products were formed in yields of 34-93%.
The present invention provides compounds of formula I
and pharmaceutically acceptable salts thereof. The formula I compounds inhibit tyrosine kinase activity of such as TrkA, TrkB, TrkC, Jak2, Jak3 and CK2, thereby making them useful as antiproliferative agents for the treatment of cancer and other diseases.
