  Nucleophilic reactions with Grignard reagents and the Mukaiyama aldol reactions of the naphthaldehydes having the (2,4, 6-triisopropylphenyl)sulfinyl group produced products with high stereoselectivity. In these reactions, the stereochemistry of the major products changes depending on the Lewis acids used. Reduction of the 2-acyl-1-[(2,4,6-triisopropylphenyl)sulfinyl]naphthalenes also proceeds with

  Sulfoxides bearing a tert-butyl group can be activated using N-bromosuccinimide (NBS) under acidic conditions and then subsequently treated with a variety of nitrogen, carbon, or oxygen nucleophiles to afford a wide range of the corresponding sulfinic acid amides, new sulfoxides, and sulfinic acid esters.

  Barriers for the EZ interconversion of atropisomers of 1-naphthyl sulfoxides (ArSOR) having a methyl group at position 2 of the naphthalene moiety were measured by variable-temperature NMR. Their values were found to cover the range 10.6-18.4 kcal mol-1, the extreme values corresponding to derivatives 1 (R = Me) and 4 (R = Bu(t)), respectively. NOE and LIS measurements indicated that the Z atropisomer is more stable than the E but that the absence of the methyl group at position 2 of the naphthalene moiety reverses this trend, rendering E more stable than Z. Solid-state NMR and X-ray diffraction of 4 established that only the more stable atropisomer (Z) is present in the crystalline state. Molecular mechanics calculations suggest that the Z,E interconversion process might occur by a rotation pathway having an opposite direction in the case of the more hindered derivatives 3 and 4 (R = Pr(i) and Bu(t), respectively) with respect to the less hindered 1 and 2 (R = Me and Et, respectively). The enantiomers, which are due to the presence of the asymmetric sulfur atom, were resolved on a chiral stationary phase (DACH-DNB) having an SS configuration. Asymmetric oxidation reactions were employed to assign the absolute R configuration to the more retained enantiomers of alkyl aryl sulfoxides. The opposite trend (S being retained longer) was observed for diaryl sulfoxides such as 5 (R = Ph). In the case of the derivative with the largest interconversion barrier, sulfoxide 4, it was also possible to resolve (at -35-degrees-C) the two enantiomeric forms and their associated atropisomers. The use of on-line CD detection and the knowledge of the NMR assignments allowed us to unambiguously assign the elution order of the four species as ES, ER, ZS, ZR.

  A diastereoselective one-pot approach to access trans-5-hydroxy-6-substituted-2-piperidinones by an addition-cyclization-deprotection process has been developed, in which the stereogenic center at the C-6 position was solely controlled by alpha-OTBS group. The utility of this transformation is demonstrated by the asymmetric synthesis of the enantiomer of (-)-CP-99,994.

  Enantiopure aromatic (phenyl, naphthyl) and heteroaromatic (pyridyl, quinolyl, diazinyl) sulfoxides have been synthesized by reaction of (S)-tert-butyl tert-butanethiosulfinate with aryl- or heteroaryllithium derivatives. The ortho-directed metalation of the sulfoxides was performed with lithium bases. Subsequent addition of the lithiated intermediates to N-tosylimines afforded tosylaminoalkyl tert-butylsulfinyl arenes. In most cases a complete asymmetric induction was highlighted in favor of (S,S) isomers. Heating the aminosulfoxides provided an original cyclization to form novel cyclic sulfenamides. A novel enantiopure synthesis of a benzylamine was described. An application of an enantiopure aminosulfoxide as N,S ligand for the asymmetric catalysis of allylic nucleophilic substitution has been successfully tested.
