Enantioselective Desymmetrization of Glutarimides Catalyzed by Oxazaborolidines Derived from cis-1-Amino-indan-2-ol

Enantioselective reductive desymmetrization of glutarimides has been achieved employing an oxazaborolidine catalyst derived from cis-1-amino-indan-2-ol. The reaction was found to proceed through a stereoablative process that upgraded the enantioselectivity of an intermediate hydroxy-lactam. The reaction was generally tolerant of a number of substituents in the 4-position, giving enantiomeric excesses of greater than 82%.

ALLOSTERIC PROTEIN KINASE MODULATORS

The invention provides specific small molecule compounds that allosterically regulate the activity or modulate protein-protein interactions of AGC protein kinases and the Aurora family of protein kinases, methods for their production, pharmaceutical compositions comprising same, and their use for preparing medicaments for the treatment and prevention of diseases related to abnormal activities of AGC protein kinases or of protein kinases of the Aurora family.

The first asymmetric synthesis of a 4-aryl-substituted 5-carboxy-3,4-dihydropyridin-2-one derivative

A simple and practical route for the asymmetric synthesis of (S)-4-(4-fluorophenyl)-1,4,5,6-tetrahydro-6-oxo-3-pyridinecarboxylic acid (1) is presented. The procedure comprises catalytic desymmetrization of a meso-anhydride using a chiral thiourea organocatalyst, followed by selective formylation and cyclization.
