Convenient, functional group-tolerant, transition metal-free synthesis of aryl and heteroaryl trifluoromethyl ketones with the use of methyl trifluoroacetate
transition metal-free route to aryl trifluoromethyl ketones under mild conditions is described. The reaction of not only aryl Grignard reagents carrying reducible electrophilic functional groups, such as ester and cyano groups, but also electron-deficient nitrogen-containing heteroaryl Grignard reagents with methyl trifluoroacetate gives the corresponding aryl or heteroaryl trifluoromethyl ketones in good
The present invention relates to compounds of Formula (I)
and their pharmaceutically acceptable salts, wherein the substituents are as described herein, and their use in medicine, in particular as Trk antagonists.
