A convergent, stereocontrolled synthesis of C2-symmetrical and pseudosymmetrical sulfur-tethered bis(amino alcohols)

The totally enantiocontrolled preparation of C2-symmetrical and pseudosymmetrical sulfur-tethered bis(amino alcohols) from anti-3-amino-1,2- alkane diols is described. The key step in the synthetic procedure involves the use of triphenylsilanethiol as a sulfide or hydrogenosulfide equivalent in the regioselective nucleophilic ring opening of both anti- and syn- aminoalkyl epoxides.

Ready access to stereodefined β-hydroxy-γ-amino acids. Enantioselective synthesis of fully protected cyclohexylstatine

A convenient entry to enantiopure syn or anti β-hydroxy-γ-amino acids is described. The starting compounds for the synthesis, anti 3-amino-1,2-diols, are readily available in high enantiomeric purity through catalytic asymmetric epoxidation of an allylic alcohol and titanium-promoted oxirane opening. After adequate protection of the nitrogen, a stereodivergent sequence leads to both anti and syn N-Boc aminoalkyl epoxides. Subsequent regioselective ring-opening with cyanide, protection of the resulting secondary alcohol and nitrile to carboxyl conversion afford, in good yields, protected β-hydroxy-γ-amino acid belonging to either the anti (erythro) or syn (threo) series. This methodology has been applied to the enantioselective preparation of cyclohexylstatine, a key component of several aspartyl protease inhibitors, in fully protected form.

A convenient, stereodivergent approach to the enantioselective synthesis of N-Boc-aminoalkyl epoxides

An efficient, stereodivergent and enantioselective synthesis of N-Boc-aminoalkyl epoxides has been developed. Starting from enantiomerically enriched anti N-diphenylmethyl-3-amino-1,2-diols, and after a change in the nitrogen protecting group, an intramol
