Toward Asymmetric Synthesis of Pentaorganosilicates

Introducing chiral silicon centers was explored for the asymmetric Rh-catalyzed cyclization of dihydrosilanes to enantiomerically enriched spirosilanes as targets to enable access to enantiostable pentacoordinate silicates. The steric rigidity required in such systems demands the presence of two naphthyl or benzo[b]thiophene groups. The synthetic approach to the expanded spirosilanes extends Takai?s method (Kuninobu et al. in Angew Chem Int Ed 52(5):1520?1522, 2013) for the synthesis of spirosilabifluorenes in which both a Si?H and a C?H bond of a dihydrosilane are activated by a rhodium catalyst. The expanded dihydrosilanes were obtained from halogenated aromatic precursors. Their asymmetric cyclization to the spirosilanes were conducted with [Rh(cod)Cl]2 in the presence of the chiral bidentate phosphane ligands (R)-BINAP, (R)-MeO-BIPHEP, and (R)-SEGPHOS, including derivatives with P-(3,5-t-Bu-4-MeO)-phenyl (DTBM) groups. The highest enantiomeric excess of 84% was obtained for 11,11?-spirobi[benzo[b]-naphtho[2,1-d]silole] with the DTBM-SEGPHOS ligand.

Deprotonative C-H silylation of functionalized arenes and heteroarenes using trifluoromethyltrialkylsilane with fluoride

A highly selective C-H silylation reaction of functionalized arenes and heteroarenes was developed using Ruppert-Prakash reagent (TMSCF3) activated by alkali metal fluoride. TMSCF3 is considered to play dual roles as a precursor of a mild base and also as a silicon electrophile. The silylation is compatible with sensitive functional groups such as halogen and nitro groups.

Asymmetric Allylic C-H Alkylation via Palladium(II)/ cis-ArSOX Catalysis

We report the development of Pd(II)/cis-aryl sulfoxide-oxazoline (cis-ArSOX) catalysts for asymmetric C-H alkylation of terminal olefins with a variety of synthetically versatile nucleophiles. The modular, tunable, and oxidatively stable ArSOX scaffold is key to the unprecedented broad scope and high enantioselectivity (37 examples, avg. > 90% ee). Pd(II)/cis-ArSOX is unique in its ability to effect high reactivity and catalyst-controlled diastereoselectivity on the alkylation of aliphatic olefins. We anticipate that this new chiral ligand class will find use in other transition metal catalyzed processes that operate under oxidative conditions.

Discovery of a new series of potent and selective linear tachykinin NK 2 receptor antagonists

Starting from 1 (MEN 14268), a selective tachykinin NK2 receptor antagonist with an interesting in vitro pharmacological profile, a family of numerous antagonists was obtained through an optimization process focused on iterated structural modifications. The effects of the introduction of a wide variety of substituents on the lipophilic aromatic part of the molecule and the modulation of the structural constraint through the insertion of different achiral alpha,alpha-dialkylamino acids were investigated. In particular, aromatic and benzofused heteroaromatic moieties were introduced at the pseudo-N-terminal residue to replace the 2-benzothiophene moiety, and a systematic investigation of the best positioning of substituents onto the aromatic platform was reported for the benzothiophene core. Studies on the modulation of the length and the rigidity of the hydrophilic pseudo-C-terminal pendant are presented. Many heteroaliphatic groups are well tolerated by the receptor in this part of the ligand. The product 48f (MEN15596), bearing a methyl substituent on the benzothiophene and a tetrahydropyranylmethylpiperidine pendant, was finally selected for its good in vivo activity after intravenous, intraduodenal, and oral administration in guinea pigs.

Discovery of novel benzo[b]thiophene tetrazoles as non-carboxylate GPR40 agonists

GPR40 partial agonism is a promising new mechanism for the treatment of type 2 diabetes mellitus with clinical proof of concept. Most of the GPR40 agonists in the literature have a carboxylic acid functional group, which may pose a risk for idiosyncratic drug toxicity. A novel series of GPR40 agonists containing a tetrazole as a carboxylic acid bioisostere was identified. This series of compounds features a benzo[b]thiophene as the center ring, which is prone to oxidation during phase 1 metabolism. Following SAR optimization targeting GPR40 agonist activity and intrinsic clearance in microsomes (human and rat), potent and metabolically stable compounds were selected for in vivo evaluation. The compounds are efficacious at lowering blood glucose in a SD rat oGTT model.
