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.
Highly stereoselective N-acyliminium ion coupling reactions of β-ketoester derived silyl enol ethers with enantiopure lactams derived from (S)-malic acid are reported. This reaction type is applied in the synthesis of the enantiopure C-2 substituted lactam 27, a plausible intermediate in a projected synthesis of ptilomycalin A.

A stereoselective synthesis of two isomers (2S,8R) and (2S,8S) of 8-methyl-2-decanol opanoate (the pheromone emitted by females of several Diabrotica species) has been accomplished using mote stereochemicalrelationshipsbetween carbons 3 and 9 of the 3,9-dimethyl decanolides 14 and 16.

A diastereoselective approach to (2R,5S)- and (2S,5S)-2-methyl-1,6-dioxaspiro[4.5]decane 1 and 1a is described. The route starts with an alkylation reaction among the cyclopentanone N,N-dimethylhydrazone 6 and the chiral iodides (R)-3 or (S)-3, derived from the enantiomers of ethyl β-hydroxybutyrate, controlling the estereocenter at C-2 of the molecules. The alkylated products 7 and 7a were easily
