Zinc mediated Barbier type propargylation of cyclic imides

Zn/ZrCl4 System Induced Reductive Cleavage of the Se–Se Bond in Diaryl Diselenides: A Novel Method for the Synthesis of β-selenoesters and β-selenonitriles

The Se–Se bond in diselenides was reduced by Zn/ZrCl4 to produce selenolate anions, which react with α,β -unsaturated esters or α,β -unsaturated nitriles to afford β-selenoesters and β-selenonitriles, respectively.

A concise gram-scale synthesis of ht-13-A via a rhodium-catalyzed intramolecular C–H activation reaction

The enantioselective total synthesis of the 3,4-fused indole alkaloid ht-13-A has been achieved.
