Synthesis of tetracyclic chromenones via platinum(ii) chloride catalysed cascade cyclization of enediyne-enones

PtCl2 catalysed cascade cyclization of an enediyne-enone system to afford a tetracyclic chromenone is reported, which proceeds through two consecutive highly regioselective 6-endo-dig cyclizations in a single step with the formation of two new C-C bonds and two new rings in excellent yield. A mechanism for this transformation is proposed based on the isolated intermediates.

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.

Highly Unsaturated Oligomeric Hydrocarbons: α-(Phenylethynyl)-ω-phenylpoly

A new set of conjugated oligomers C6H5CC-(1,2-C6H4CC)n-C6H5 (10; n=3-7) comprised of acetylene and phenyl units linked together at the 1,2 positions of the aromatic ring is introduced.The facile synthesis of these compounds is achieved through the Pd-medi
