The present invention provides a compound of Formula (1) as described herein or a pharmaceutically acceptable salt, solvate or ester thereof. The compounds are useful as inhibitors of the HDM2 protein. Also disclosed are pharmaceutical compositions comprising the above compounds and methods of treating cancer using the same.
The coupling of primary and secondary unactivated alkyl bromides with alkyl-Grignard reagents was performed in good yields under mild conditions by using a new catalytic system: consisting of cobalt chloride and tetramethylethylenediamine (CoCl2⋅2 LiI, 4 TMEDA). The reaction is very chemoselective since ketone, ester and nitrile functions are tolerated.

Takai–Utimoto reactions with secondary and tertiary aliphatic halides usually failed according to previous reports. Now, significant improvements could be achieved, and especially secondary aliphatic halides can be coupled to aromatic aldehydes in yields of up to >95%. A variety of processes are competing with the desired one, and thus conditions must be adapted to the nature of the aldehyde as well
The present invention relates to a compound of formula I, racemates, optically active isomers, or pharmaceutically acceptable salts or solvates thereof, and a pharmaceutical composition comprising the compound, the various radicals in the formula I are the same as defined in the claims. The present invention also relates to a process for preparing the compound of formula I and use of said compound in the preparation of a medicament for the treatment of hyperglycemia, dyslipidemia, type II diabetes mellitus including associated diabetic dyslipidemia
