Dual-action catalyst: A Bronsted acid catalyzed regioselective cycloisomerization was found to be highly effective for the preparation of structurally diverse 2,3-dihydro-4H-pyran-4-ones in a 6-exo-trig manner from the corresponding 5,2-enyne-1-ones. In t

Mild, efficient, and clean! Six-membered cyclic products including diiodocyclohexadiene and 2,3-diiodobenzene have been prepared in a iodonium-induced internal carbocyclization of hydroxylated enynes (see scheme). This reaction proceeds smoothly under mild reaction conditions, and all the halogen atoms (I and Br) generated from the electrophiles are used effectively.
Gold(I) catalyzed isomerization of 5-en-2-yn-1-yl acetates: An efficient access to acetoxy bicyclo[3.1.0]hexenes and 2-cycloalken-1-ones

The gold(I) catalyzed rearrangement of 5-en-2-yn-1-yl acetates into functionalized acetoxy bicyclo[3.1.0]hexenes is described. The mild reaction conditions employed allow the efficient and rapid synthesis of a variety of such bicyclic compounds via a sequence of two gold(I)-catalyzed isomerization steps. Acetoxy bicyclo[3.1.0]hexenes products can be further transformed to 2-cycloalkenones by simple methanolysis. Copyright
