A method for asymmetric alkyl-alkylSuzuki reactions of unactivatedsecondaryalkyl electrophiles, specifically, cross-couplings of racemic acylated halohydrins with alkylborane reagents, has been developed. A range of protected bromohydrins, as well as a protected chlorohydrin and a homologated bromohydrin, are coupled in good ee by a catalyst derived from commercially available components.

Indole and indole-related compounds, compositions and methods are disclosed. The compounds of the invention are useful as phospholipase inhibitors. The compounds and compositions of the invention are useful for treatment of phospholipase-related conditions, such as insulin-related, weight-related and/or cholesterol-related conditions in an animal subject.
A novel series of cathepsinKinhibitors derived from Novartis compound I is described. Optimization of the P1, P3, and P1' units led to the identification of 4-aminophenoxyacetic acid 24b with an IC(50) value of 4.8 nM, which possessed an excellent selectivity over other human cathepsins and good pharmacokinetic (PK) properties. Oral administration of compound 24b to ovariectomized (OVX) rats showed
