Conjugate additions of organometallic reagents to α,β-unsaturated carboxylic acidderivatives give access to numerous β-substituted chiral building blocks. Chiral oxazolidinones serve as useful surrogates of carboxylic function in the asymmetric conjugate addition of Grignardreagents. N-Enoyl oxazolidinones undergo this 1,4-addition with a catalytic amount of copper salt and using either chiral or
The present invention relates to compounds of the formula (I), which are useful in treating diseases characterized by, the hyperactivity of MEK. Accordingly the compounds are useful in the treatment of diseases, such as, cancer, cognative and CNS disorders and inflammatory/autoimmune diseases.
