The invention is directed to piperidinyl compounds of formula (I) and (II) that selectively bind integrin receptors and methods for treating an integrin mediated disorder, wherein W, R2, Z and q are described in the application.
An efficient method for stereoselective nitroaminoxylation of alkyne has been reported. The reaction enjoys a broad substrate scope, good functional group tolerance, and high yields. Synthetically useful α-nitroketones can be accessed through these products in a single step.

Activation of 3-((trimethylsilyl)ethynyl)pyridine with triflicanhydride followed by nucleophilic addition of bis(trimethylsili) ketene acetals and a unusual alkyne hydration allowed to obtain new series of 3-acetylated dihydropyridine acids 3a-h in a single step. Secondly, docking studies were conducted on four of the test compounds (3b, 3e, 17a and 17b) and a reference drug (fluconazole) at the active

of trifluoromethylated alkenes by the radical-mediated trifluoromethylation of vinyltrifluoroborates has been developed. Togni's reagent serves as a CF(3) radical precursor in the presence of the photoredox catalyst [Ru(bpy)(3)](PF(6))(2) under visible light irradiation. This new photocatalytic protocol can be applicable to a wide variety of vinylborates containing electronically diverse substituents
