Two stable degradants of palladium tBuXPhos catalyst have been synthesized from tBuXPhos and Pd2(dba)3CHCl3, isolated, and fully characterized. Complex 2 augments the known literature examples of palladacycles from this ligand family but is present as a rare four-membered-ring palladacycle, having activated the top ring of the ligand. Complex 3 is an unusual case of palladium-mediated dearomatization, whereby chloroform functionalizes the bottom ring, generating a palladium allyl complex. The mechanism is assigned to an electrophilic carbene attack where palladium directs attack of dichlorocarbene to the anti face of the bottom arene. The structures have been confirmed by NMR and single-crystal X-ray diffraction.

A series of monoligated L?PdII(Ar)X complexes (L = dialkyl biaryl phosphine) have been prepared and studied in an effort to better understand an unusual dearomative rearrangement previously documented in these systems. Experimental and theoretical evidence suggest a concerted process involving the unprecedented PdII-mediated insertion of an aryl group into an unactivated arene.

A Pd complex, cis-[Pd(C6F5)2(THF)2] (1), is proposed as a useful touchstone for direct and simple experimental measurement of the relative ability of ancillary ligands to induce C?C coupling. Interestingly, 1 is also a good alternative to other precatalysts used to produce Pd0L. Complex 1 ranks the coupling ability of some popular ligands in the order PtBu3>o-TolPEWO-F?tBuXPhos>P(C6F5)3?PhPEWO-F>P(o-Tol)3?THF?tBuBrettPhos?Xantphos?PhPEWO-H?PPh3according to their initial coupling rates, whereas their efficiency, depending on competitive hydrolysis, is ranked tBuXPhos?PtBu3?o-TolPEWO-F>PhPEWO-F>P(C6F5)3?tBuBrettPhos>THF?P(o-Tol)3>Xantphos>PhPEWO-H?PPh3. This ?meter? also detects some other possible virtues or complications of ligands such as tBuXPhos or tBuBrettPhos.

The first general palladium catalyst for the phosphorylation of aryl mesylates and tosylates is reported. The newly developed system exhibits excellent functional group compatibility. For instance, free amino, keto, ester, and amido groups, as well as heterocycles, remain intact during the course of reaction. The mesylated derivatives of biologically active compounds such as 17beta-estradiol and 6-hydroxyflavone are also shown to be applicable substrates. A one-pot phosphorylation-amination sequence is described for the facile synthesis of potential pharmacophores.

A novel and potent small molecule glucagon receptor antagonist for the treatment of diabetes mellitus is reported. This candidate, (S)-3-[4-(1-{3,5- dimethyl-4-[4-(trifluoromethyl)-1H-pyrazol-1-yl]phenoxy}butyl)benzamido] propanoic acid, has lower molecular weight and lipophilicity than historical glucagon receptor antagonists, resulting in excellent selectivity in broad-panel screening, lower cytotoxicity, and excellent overall in vivo safety in early pre-clinical testing. Additionally, it displays low in vivo clearance and excellent oral bioavailability in both rats and dogs. In a rat glucagon challenge model, it was shown to reduce the glucagon-elicited glucose excursion in a dose-dependent manner and at a concentration consistent with its rat in vitro potency. Its properties make it an excellent candidate for further investigation.

A novel 4-aminoindazole sulfonamide hit (13) was identified as a human CCR4 antagonists from testing a focussed library of compounds in the primary GTPgammaS assay. Replacing the indazole core with a pyrazolopyrimidine, and introduction of a methoxy group adjacent to the sulfonamide substituent, resulted in the identification of pyrazolopyrimidine 37a, which exhibited good binding affinity in the GTPgammaS assay (pIC50 = 7.2), low lipophilicity (c log P = 2.2, chromlog D7.4 = 2.4), high LE (0.41), high solubility (CLND solubility ?581 muM), and an excellent PK profile in both the rat (F = 62%) and the dog (F = 100%). Further SAR investigation of the pyrazolopyrimidine suggested that substitution at N1 is tolerated, providing a suitable vector to modulate the properties, and increase the potency in a lead optimisation campaign.
