Seven chiral analogues of tosylmethyl isocyanide (TosMIC) were synthesized in order to investigate and compare their ability to achieve asymmetricinduction in base mediated reactions with acetophenone and trifluoroacetophenone. Acid hydrolysis of the intermediate 2-oxazolines (10 and 11) gave optically active α-hydroxy aldehydes (12 and 13).

The present invention provides a compound of formula (I): and pharmaceutically acceptable salts, enantiomers, stereoisomers, rotamers, tautomers, diastereomers, or racemates thereof. These compounds inhibit the activity of CDK9 and are thus useful as pharmaceuticals. Also provided are methods of treating a disease or condition mediated by CDK9 using the compounds of Formula I and isomers thereof, and pharmaceutical compositions comprising such compounds.
