An Unexpected Domino Reaction of β-Keto Sulfones with Acetylene Ketones Promoted by Base: Facile Synthesis of 3(2H)-Furanones and Sulfonylbenzenes

An unexpected domino reaction of β-keto sulfones with acetylene ketones has been developed. The domino reaction of β-keto sulfones with diynones proceeded smoothly in the presence of 30 mol% K2CO3 without other additives, and afforded the novel 3(2H)-furanone derivatives. On replacing the diynones with terminal alkyne ketones, the reaction regioselectivity was changed and sulfonylbenzenes were obtained via benzannulation in good yields. (Figure presented.).

Bronsted acid catalyzed and NIS-promoted cyclization of diynones: Selective synthesis of 4-pyrone, 4-pyridone, and 3-pyrrolone derivatives

Bronsted acid catalyzed tandem cyclization was found to be highly effective for the preparation of a series of polysubstituted 4-pyrones from diynones (yield up to 99%). 4-Pyridone and 3-pyrrolone derivatives were also selectively synthesized by employing NIS and/or Bronsted acid. NIS as an electrophilic reagent could promote these reactions efficiently and rapidly under very mild reaction conditions.

Synthesis of simple diynals, diynones, their hydrazones, and diazo compounds: Precursors to a family of dialkynyl carbenes (R1-C-C- C-C-C-R2)

A variety of substituted pentadiynols, -diynals, and -diynones have been prepared en route to precursors to dialkynyl carbenes (R1-C-C-C- C-C-R2). In light of the marginal stability associated with these simple systems, several strategies were required to assemble the carbon backbones. The requisite five-carbon skeletons were prepared using 4 + 1, 3 + 2, 2 + 2 + 1, and 2 + 1 + 1 + 1 coupling methodologies. The Dess-Martin periodinane serves as an excellent method for the oxidation of pentadiynols to diynals and diynones, although many of the oxidized products are sufficiently reactive that they were not isolated; rather, they were generated in situ and intercepted with nucleophiles such as tosylhydrazide or trisylhydrazide. The hydrazone derivatives are generally reliable precursors to diazo compounds and carbenes, although cyclization of the hydrazone to afford a pyrazole can be a complicating factor in certain instances.

Tert-butyl-end-capped polyynes: Crystallographic evidence of reduced bond length alternation

Cumulene or polyyne? The synthesis and X-ray crystallographic analysis of a series of polyynes up to 20 Csp atoms in length and end-capped with tert-butyl groups has been achieved. The structural data show a distinct reduction in the bondlength alternation as a function of the polyyne length, but this trend appears to saturate before a cumulenic-like structure is achieved.
