- Synthesis of Enantiomerically Enriched α-Sulfenylated Ketones and Aldehydes
-
α-Sulfenylated carbonyl compounds are prepared by the reaction of imines of aldehydes and ketones containing α-hydrogens with disulfides via the metalloenamines.With (R)-α-phenylethylamine as chiral auxiliary, enantiomeric excess of 13-51percent are obser

- Efficient Functional Group Transformations on a Cyclic Nitroalkene System
-
Single-pot nitroalkene -> cyanoaldehyde transformation, α-methoxy oxime formation, α- and β-alkylations of β-sulphenylated nitro compound, generation of β-sulphenylated nitro compound, generation of β-sulphenylated silyl nitronate, and sequential Michael addition and Nef reaction have been accomplished in good to excellent yields.
