Synthesis of Functionalized 1H-Isochromene Derivatives via a Au-Catalyzed Domino Cycloisomerization/Reduction Approach

Synthesis of dihydroindeno[1,2-c]isochromene via cascade cyclization and Friedel–Crafts reaction

Dihydroindeno[1,2-c]isochromene can be efficiently prepared from alkynol and aldehydesviacascade cyclization and Friedel–Crafts reaction. The reaction is highly regioselective.

Exploring the gold mine: [Au]-catalysed transformations of enynals, enynones and enynols

This review highlights reactions of enynals, enynones and enynols using gold catalysis which often lead to cycloaddition or cyclisation products.

Gold-catalyzed π-directed regioselective cyclization of bis(o-alkynyl benzyl alcohols): rapid access to dihydroisobenzofuran derivatives

A tandem alkyne/alkene-directed 5-exo-dig cyclization and a Prins-type cyclization for the synthesis of dihydroisobenzofurans are described.

Tetracyclic dihydronaphthalene derivatives via gold-catalyzed aminative homodimerization of ortho-alkynylbenzaldehydes

o-Alkynylbenzaldehydes undergo gold-catalyzed aminative homodimerization via a domino 6-endo-dig/hydroamination/[4+2] cycloaddition reaction sequence, furnishing tetracyclic products that incorporate medicinally relevant moieties.
