A practical and straightforward approach for the highly stereoselective synthesis of β-amino sulfones was developed. With lithium bis(trimethylsilyl)amide as the base, the corresponding sulfone-stabilized carbanion derived from alkylphenyl sulfone can be transferred to N-(tert-butylsulfinyl) aldimines in excellent yields and with high diastereoselectivity.

β‐Amino acid analogues: The nucleophilic addition of ethyl (diethoxyethyl)methylphosphinate to a variety of (S)‐(tert‐butanesulfinyl)imines leads to the isolation of two enantioenriched β‐aminophosphinates (>95 % ee; see scheme). Subsequent removal of the protecting groups through pivotal metal‐catalyzed thiophenolysis leads to optically pure ethylβ‐amino‐H‐phosphinates.

Asymmetric synthesis and biological evaluation of N-cyclohexyl-4-[1-(2,4-dichlorophenyl)-1-(p-tolyl)methyl]piperazine-1-carboxamide as hCB1 receptor antagonists
We recently discovered and reported a novel series of benzhydrylpiperazine derivatives bearing an asymmetric carbon atom that are potent and selective hCB1 inverse agonists. In the present study, we used Davis-Ellmann-type sulfonamide chemistry to asymmetrically synthesize two enantiomers of the most potent racemic N-cyclohexyl-4-[1-(2,4-dichlorophenyl)-1-(p-tolyl)methyl]piperazine-1-carboxamide [14]. Enantiomer separation and configuration assignment were carried out. Our results indicate that the R-configuration is the more active enantiomer, displaying enhanced antagonistic activity for hCB1 receptor, better oral bioavailability, and greater efficacy in the reduction of body weight in diet-induced obese mice.
