Regioselective cyclizations utilizing a gold-catalyzed [3,3] propargyl ester rearrangement

Switch-Au-roo: A new strategy for the regioselective synthesis of unsaturated carbocycles by chemoselective activation of a Rauhut-Currier zwitterion surrogate, formed from the Au-catalyzed [3,3] sigmatropic rearrangement of propargylic esters, has been achieved. By reversing the regiochemistry of the propargyl ester the synthesis of either the endo- or exocyclic enones is feasible.
Vicinal bisheterocyclizations of alkynes via nucleophilic interception of a catalytic platinum carbene
Allegretti, Paul A.,Ferreira, Eric M.
, p. 17266 - 17269 (2014/01/06)
A novel platinum-catalyzed double heterocyclization of propargylic ethers is described. The transformation exploits the intermediacy of a key α,β-unsaturated carbene. The reactivity of this carbene is such that systems can be developed which avoid a complicating 1,2-hydrogen migration, allowing remarkable versatility in the selective syntheses of oxygen- and nitrogen-containing vicinal bis-heterocyclic compounds.

An efficient PtI2-catalyzed tandem reaction of arylpropargylic esters, involving 3,3-rearrangement and Nazarov reaction, has been developed to produce 3-substituted and 3,3-disubstituted indanone derivatives. This approach provided a pathway to the synthesis of indanone skeletons in natural products.
