Cobalt-catalyzed hydrohydrazination of dienes and enynes: Access to allylic and propargylic hydrazides

(Chemical Equation Presented) The cobalt-catalyzed hydrohydrazination reaction of dienes and enynes is presented. Allylic and propargylic hydrazines were obtained in synthetically useful yields (allylic amines, 60-90%; propargylic amines, 47-83%) and good chemo- and regioselectivity.

Gold catalyzed efficient preparation of dihydrobenzofuran from 1,3-enyne and phenol

A gold catalyzed formal intermolecular [2+3] cyclo-coupling of 1,3-enynes with phenols was developed to prepare dihydrobenzofuran derivatives with the addition of 2,6-dichloropyridine N-oxide, in which, a highly ortho-selective phenol SEAr functionalizati

Hydromagnesiation of 1,3-Enynes by Magnesium Hydride for Synthesis of Tri- and Tetra-substituted Allenes

A protocol for regio-controlled hydromagnesiation of 1,3-enynes was developed using magnesium hydride that is generated in situ by solvothermal treatment of sodium hydride (NaH) and magnesium iodide (MgI2) in THF. The resulting allenylmagnesium species could be converted into tri- and tetra-substituted allenes by subsequent treatment with various carbon- and silicon-based electrophiles with the aid of CuCN as a catalyst.

Regioselective Access to 3-Ethylideneflavanones via Rhodium(I)-Catalyzed 1,3-Enyne Hydroacylation/Annulation Cascades

The highly efficient synthesis of 3-ethylideneflavanones through sequential rhodium(I)-catalyzed hydroacylation of terminal aryl-substituted 1,3-enynes with chelating aldehydes and annulation is described. This straightforward protocol highlights an unprecedented C3-regioselective hydroacylation of 1,3-enynes, excellent functional group compatibility, and complete atom economy. (Figure presented.).
