Discovery and Characterization of (R)-6-Neopentyl-2-(pyridin-2-ylmethoxy)-6,7-dihydropyrimido[2,1-c][1,4]oxazin-4(9H)-one (PF-06462894), an Alkyne-Lacking Metabotropic Glutamate Receptor 5 Negative Allosteric Modulator Profiled in both Rat and Nonhuman Primates

We previously observed a cutaneous type IV immune response in nonhuman primates (NHP) with the mGlu5 negative allosteric modulator (NAM) 7. To determine if this adverse event was chemotype- or mechanism-based, we evaluated a distinct series of mGlu5 NAMs. Increasing the sp3 character of high-throughput screening hit 40 afforded a novel morpholinopyrimidone mGlu5 NAM series. Its prototype, (R)-6-neopentyl-2-(pyridin-2-ylmethoxy)-6,7-dihydropyrimido[2,1-c][1,4]oxazin-4(9H)-one (PF-06462894, 8), possessed favorable properties and a predicted low clinical dose (2 mg twice daily). Compound 8 did not show any evidence of immune activation in a mouse drug allergy model. Additionally, plasma samples from toxicology studies confirmed that 8 did not form any reactive metabolites. However, 8 caused the identical microscopic skin lesions in NHPs found with 7, albeit with lower severity. Holistically, this work supports the hypothesis that this unique toxicity may be mechanism-based although additional work is required to confirm this and determine clinical relevance.

Amino alcohol-derived chiral ionic liquids: structural investigations toward chiral recognition

From tentative beginnings, chiral ionic liquids have emerged into functionalized and tailor-made materials that provide novel input in classical asymmetric synthesis and separations. However, despite this broad application range the prediction of any chiral ionic liquids' performance is difficult. We present a systematic study toward the chiral recognition properties of novel ionic liquids with an amino alcohol sub-structure derived from the chiral pool precursors ephedrine, prolinol, and phenylalaninol. The influence of different ionic head groups and core structures on the diastereomeric interactions between racemic Mosher's acid carboxylate and enantiopure chiral ionic liquids was systematically investigated to provide insight into their recognition properties prior to application of these chiral ionic liquids in various fields.

Diastereoselective synthesis of novel 5-substituted morpholine-3-phosphonic acids: Further exploitation of N-acyliminium intermediates

The first diastereoselective total synthesis of 5-substituted morpholine-3-phosphonic acids is reported. The principal feature of the synthesis is the introduction of a dimethyl phosphonate group into 5-substituted morpholin-3-ones. The procedure is based

Enantioselective Hydrosilylation of Ketones Catalyzed by a Readily Accessible N-Heterocyclic Carbene-Ir Complex at Room Temperature

A series of functionalized azolium compounds were synthesized from chiral α-amino acid derivatives such as β-amino alcohols. of hydroxy-amide-functionalized azolium salts thus obtained with Ag2O afforded N-heterocyclic carbene-Ag (NHC-Ag) complexes. Subsequent treatment of the resulting silver compound with [IrCl(cod)]2 yielded monodentate IrCl(cod)(NHC), which was stable in air. The NHC-Ir complex facilitated efficient asymmetric hydrosilylation of ketones using (EtO)2MeSiH under ambient conditions. A chiral ligand containing an isobutyl stereodirecting group was found to be the best ligand for the functionalized NHC-Ir complexes that were examined. A linear relationship was found between the catalyst ee and the product ee. The hydroxy functional group on the NHC ligand side-arm not only induced stereocontrol but also enhanced the reaction rate.

Amine-promoted asymmetric (4+2) annulations for the enantioselective synthesis of tetrahydropyridines: A traceless and recoverable auxiliary strategy

Gone, without a trace: The in situ reaction of 2-(acetoxymethyl)buta-2,3- dienoate and a secondary amine produces a 2-methylene-3-oxobutanoate equivalent that can be used in asymmetric [4+2] annulations with N-tosylimines to provide tetrahydropyridines in

Organic base effects in NHC promoted O- to C-carboxyl transfer; Chemoselectivity profiles, mechanistic studies and domino catalysis

The O- to C-carboxyl transfer of oxazolyl carbonates promoted by triazolinylidenes, generated in situ with NEt3, shows a markedly different rate and chemoselectivity profile to the same reaction promoted by triazolinylidenes generated using KHM

Catalytic enantioselective Steglich rearrangements using chiral N-heterocyclic carbenes

The evaluation of a range of enantiomerically pure NHCs, prepared in situ from imidazolinium or triazolium salt precatalysts, to promote the catalytic enantioselective Steglich rearrangement of oxazolyl carbonates to their C-carboxyazlactones, is reported. Modest levels of enantioselectivity (up to 66% ee) are observed using oxazolidinone derived NHCs.
