Abstract
A synthetic route to orthogonally protected, enantiomerically pure 2-substituted piperazines is described. Starting from α-amino acids, within four steps chiral 2-substituted piperazines are obtained. The key transformation involves an aza-Michael addition between an orthogonally bis-protected chiral 1,2-diamine and the in situ generated vinyl diphenyl sulfonium salt derived from 2-bromoethyl-diphenylsulfonium triflate. Further validation using different protecting groups as well as synthesis on multigram scale was performed. The method was also applied to the construction of chiral 1,4-diazepanes and 1,4-diazocanes. Additionally, the method was utilized in a formal synthesis of chiral mirtazapine.

Abstract
We have designed, synthesized and evaluated a series of new compounds with the goal to identify potent and selective D(3) ligands. The two most potent and selective new D(3) ligands are compounds 38 and 52, which bind to the D(3) receptors with a K(i) value of <nM and display a selectivity of 450-494 times over the D(2) receptors and >10,000 times over the D(1) receptors. Both 38 and 52 are full agonists with high potency at the D(3) receptor in a D(3) functional assay.

Abstract
A series of compounds structurally related to pramipexole were designed, synthesized, and evaluated as ligands for the dopamine 3 (D3) receptor. Compound 12 has a K(i) value of 0.41 nM to D3 and a selectivity of >30000- and 800-fold over the D1-like and D2 receptors, respectively. Our in vivo functional assays showed that this compound is a partial agonist at the D3 receptor with no detectable activity at the D2 receptor.

Abstract
The asymmetric synthesis of chiral piperazinylpropylisoxazoline analogues, (R)-(+)-1, 2 and (S)-(-)-1, 2 was accomplished through a seven-step sequence of reactions, which involved asymmetric 1,3-dipolar cycloaddition, alkyl chain extension, and reductive amination as key reactions. Chiral ligands (R)-(+)-1, 2 exhibited the higher binding affinity and selectivity for the D(3) receptor over the D(4) receptor than (S)-(-)-1, 2 ligands.

Abstract
Enantiopure 1-benzyl-2,3-disubstituted piperazines (4) have been synthesized by treatment of N-sulfinyl-N-benzyldiamino alcohols (1) with diethyl oxalate and sodium methoxide followed by reduction with borane. Alternatively, the sulfinamido group was preserved by an N-acylation/cyclization protocol using alpha-chloroacetyl chloride that led to the synthesis of N-sulfinyl ketopiperazines (11). Ensuing elimination of the sulfinyl group with NaH produced imino ketopiperazines (9) that are suitably functionalized for nucleophilic addition to the imino moiety. Stereoselective and high yielding allylation of imino ketopiperazines (9c) was achieved under Barbier conditions using CeCl3.7H2O as the additive.

Abstract
We have recently reported hexahydropyrazinoquinolines as a new class of dopamine 3 (D(3)) receptor ligands with high-affinity to the D(3) receptor and excellent selectivity over the closely related D(1)-like and D(2)-like receptors. However, our previously reported most potent and selective D(3) ligands have poor aqueous solubility, which greatly hinders our in vivo studies aimed at evaluation of their therapeutic potential in animal models. In this study, we wish to report the design, synthesis, and evaluation of a series of new hexahydropyrazinoquinolines as D(3) ligands with improved solubility. Among them, compound 4g has a K(i) value of 9.7 nM for the D(3) receptor and displays a selectivity of >5000 and 466 times over the D(1)-like and D(2)-like receptors, respectively. Importantly, the hydrochloride salt form of compound 4g has a good aqueous solubility (>50 mg/mL) and represents a promising D(3) ligand for further in vivo evaluations of its therapeutic potential for the treatment of drug abuse, restless legs syndrome, schizophrenia, Parkinson's disease, and depression.
