- ORGANIC REACTIONS WITHOUT SOLVENT: MICHAEL ADDITIONS ON AN UNSATURATED SULFONE AND SULFOXIDE
-
Solid-liquid phase transfer catalysis in the absence of any solvent efficiently promotes Michael additions of nitro alkanes and of diethyl N-acetylaminomalonate to phenyl vinyl sulfone and to phenyl vinyl sulfoxide.The adduct of the Michael addition to di

- New Synthetic Methods. Conjugate Addition of Alkyl Groups to Electron Deficient Olefins with Nitroalkanes as Alkyl Anion Equivalents
-
The sequence of the Michael addition of nitroalkanes and denitration from the adduct provides a new and general method for conjugate addition of primary and secondary alkyl groups to electron deficient olefins such as α,β-unsaturated aldehydes, ketones, esters, nitriles, sulfoxides, and sulfones.

- CONJUGATE ADDITION OF ALKYL GROUPS TO α,β-UNSATURATED SULFOXIDES VIA MICHAEL ADDITION OF NITROPARAFFINS AND SUBSEQUENT DENITRATION WITH TRIBUTYLTIN HYDRIDE
-
Michael addition of nitroparaffins to α,β-unsaturated sulfoxides is well effected in the presence of DBU.The nitro group in the adduct is replaced by hydrogen with Bu3SnH without influence to the sulfinyl function.The overall reactions provide an efficien
