An efficient palladium-catalyzed oxidative C-C bond forming cascade reaction of allenes involving a coupling between an enallene and an allenyne followed by a carbocyclization of the generated Pd-intermediate was developed. This cascade reaction afforded functionalized cross-conjugated polyenes. The enallene is initially activated by palladium and reacts with the allenyne to give the cross-conjugated polyenes.

The heptakis(2,3,6-tri-O-methyl)-β-cyclodextrin (TRIMEB) has been successfully used as convenient chiral solvating agent to determine the enantiomeric composition of chiral trisubstituted allenes by 1H NMR spectroscopy: the analysis of the effect of the molar ration TRIMEB/allene, temperature, and nature of the solvent allowed us to optimize the experimental conditions to enhance the separation between the signals of the two enantiomers of each allene.

The absolute R configuration has been assigned to the dextrorotatory 1-bromo-3,4,4-trimethyl-1,2-pentadiene by relation to compounds of known configuration; this result has been used to clarify the stereochemistry of the conversion of tertiary propargylic alcohols into bromoallenes by HBr-CuBr.
