New tetrahydropyridinyl and piperidinyl ethylamine derivatives were designed with hypothetical mapping on pharmacophore model generated from ligand-based virtual screening. The designed compounds were synthesized, and their inhibitory activities on T-type calcium channel were assayed using FDSS and patch-clamp assay. Among them, compounds 7b and 10b showed potent T-type calcium current blocking activity against Cav3.1 (α 1G) and Cav3.2 (α1H) channel simultaneously. With hERG and pharmacokinetics studies, compounds 7b and 10b were evaluated for the antinociceptive effect on rat model of neuropathic pain. They were significantly effective in decreasing the pain responses to mechanical and cold allodynia induced by spinal nerve ligation. These results suggest that modulation of α1G and α1H subtype T-type calcium channels may provide a promising approach for the treatment of neuropathic pain.

The development and characterization of enantioselective organocatalytic oxidative kinetic resolution (OKR) of racemic secondary alcohols using chiral alkoxyamines as precatalysts are described. A number of chiral alkoxyamines have been synthesized, and their structure-enantioselectivity correlation study in OKR has led us to identify a promising precatalyst, namely, 7-benzyl-3-n-butyl-4-oxa-5-azahomoadamantane, which affords various chiral aliphatic secondary alcohols (ee up to >99%, krel up to 296). In a mechanistic study, chlorine-containing oxoammonium species were identified as the active species generated in situ from the alkoxyamine precatalyst, and it was revealed that the chlorine atom is crucial for high reactivity and enantioselectivity. The present OKR is the first successful example applicable to various unactivated aliphatic secondary alcohols, including heterocyclic alcohols with high enantioselectivity, the synthetic application of which is demonstrated by the synthesis of a bioactive compound.

A general and effective palladium system for Suzuki-Miyaura coupling of alkenyl electrophiles under mild reaction conditions is reported. With the Pd(OAc)2/CM-phos system, a variety of alkenyl tosylates are coupled well with ArB(OH)2. Moreover, the first successful examples of using alkenyl mesylates in alkenylation are also described.

Aryl-tetrahydropyridine derivatives were prepared and their PPARα/γ dual agonistic activities were evaluated. Among them, compound (S)-5b was identified as a potent PPARα/γ dual agonist with an EC50 of 1.73 and 0.64 μM in hPPARα and γ, respectively. In diabetic (db/db) mice, compound (S)-5b showed good glucose lowering efficacy and favorable pharmacokinetic properties.

Cheap, readily available, air stable, nontoxic, and environmentally benign iron salts such as Fe(acac)3 are excellent precatalysts for the cross-coupling of Grignard reagents with alkenyl triflates and acid chlorides. Moreover, it is shown that dichloroarene and -heteroarene derivatives as the substrates can be selectively monoalkylated by this method. All cross-coupling reactions proceed very rapidly under notably mild conditions and turned out to be compatible with a variety of functional groups in both reaction partners. A detailed analysis of the preparative results suggests that iron-catalyzed C-C bond formations can occur via different pathways. Thus, it is likely that reactions of methylmagnesium halides involve iron-ate complexes as the active components, whereas reactions of Grignard reagents with two or more carbon atoms are effected by highly reduced iron-clusters of the formal composition [Fe(MgX)2]n generated in situ. Control experiments using the ate-complex [Me4Fe]Li2 corroborate this interpretation.
