A variety of Ni(II) complexes with a wide range of electronic and steric properties, bearing picolyl-imidazolidene ligands (a-g) and Cp (2a-f) or Cp* (3a,c,g) groups, have been synthesised and characterised using NMR and single crystal X-ray crystallography. The complexes have been used as precatalysts for a wide range of catalytic transformations most likely involving a Ni0/NiII catalytic cycle. In
In order to find non-narcotic analgesics, 54 compounds of amino-tert-alcohol, in which a variety of substituent groups were involved at the carbon atom in 1-position and at the amino group, were synthesized by reacting various α-and β-amino acid esters with Grignard reagents. These amino acid esters were readily reacted with alkyl Grignard reagents to give the expected compounds. However, when bulky aromatic Grignard reagents were submitted to react, the reactions were found to stop at the stage of intermediate formation of the corresponding ketones.

The invention is directed to a method of inhibiting FLT3 tyrosine kinase activity or expression or reducing FLT3 kinase activity or expression in a cell or a subject comprising the administration of a farnesyl transferase inhibitor and a FLT3 kinase inhibitor selected from compounds of Formula I′:
Included within the present invention is both prophylactic and therapeutic methods for treating a subject at risk of (or susceptible to) developing a cell proliferative disorder or a disorder related to FLT3.
A method of reducing or inhibiting kinase activity of C-KIT in a cell or a subject, and the use of such compounds for preventing or treating in a subject a cell proliferative disorder and/or disorders related to C-KIT using a compound of the present invention:
or a solvate, hydrate, tautomer or pharmaceutically acceptable salt thereof. The present invention is further directed to methods for treating conditions such as cancers and other cell proliferative disorders.

Treatment of nitriles with alcohol and chlorotrimethylsilane at 50°C for 4 h could give esters in fair to good yields. Under similar reaction conditions, intramolecular lactonization via the concomitant nitrile and hydroxy groups in good yield were also demonstrated.
