Integrated Chemical Process: One-Pot Double Elimination Method for Acetylenes

A novel one-pot process for synthesis of acetylenes has been achieved in which the following series of steps are integrated: addition of an α-anion of sulfone to aldehyde; trapping of the resulting adduct to incorporate a leaving group, and double elimination of this intermediate. Consolidation of Peterson elimination renders the process much simpler. This method provides a convenient and high-yielding access to a variety of enynes and polyynes as well as to functionally substituted aryl acetylenes containing halogen(s) or acetal groups, which are useful building blocks for aryl acetylene scaffolds. Iteration of the one-pot generation of acetylenic bonds provides a new metodology for the buildup of aryl acetylene skeletons.

Lithio Styryl Sulfone as an Acyl Anion Synthon

Lithio styryl sulfone, which was shown to be an acyl anion synthon, reacted with various electrophiles; the products were rearranged by treatments with m-chloroperbenzoic acid to give acyl benzyl sulfones in good yields.
