The cross coupling reaction of diethoxyphosphinyldifluoromethylcadmium reagent with aryl iodides was promoted by CuCl under mild conditions to give α,α-difluoro benzylic phosphonates in good yields. A variety of functional groups, including halides, phosphonate, nitro, ketone, carboxylic acid and ester in aryl iodides, could be tolerated. This methodology has been successfully applied to prepare α,α-difluoro Fostedil 9.

The eukaryotic initiation factor 4E (eIF4E) plays a central role in the initiation of gene translation and subsequent protein synthesis by binding the 5′ terminal mRNA cap structure. We designed and synthesized a series of novel compounds that display pot

The development of low μM inhibitors of the Mycobacterium tuberculosis phosphatase PtpA is reported. The most potent of these inhibitors (Ki = 1.4 ± 0.3 μM) was found to be selective when tested against a panel of human tyrosine and dual-specif
Solid-phase synthesis of potential protein tyrosine phosphatase inhibitors via the Ugi four-component condensation

, p. 2443 - 2446 (2007/10/03)
A library of 108 α,α-difluoromethylenephosphonic acids was prepared by Ugi four-component condensation using Rink-NH2 resin, 4- [(diethoxyphosphinyl)difluoromethyl]benzoic acid, and a set of 18 aldehydes and 6 isonitriles. Following resin cleavage, the diethylphosphonate esters were hydrolyzed with trimethylsilyl bromide to yield the free acids which were assayed for inhibition of PTPα, PTPβ and PTPε.
