Novel [2,3]-sigmatropic rearrangements of oxonium ylides generated from α-oxo gold carbenes were discovered. An efficient synthetic method of 2,5-disubstituted dihydrofuran-3(2H)-ones via gold-catalyzed intermolecular oxidation of the allyl homopropargyl ethers with N-oxide was developed. And the synthetic utility of the current method has been proved by concise formal synthesis of (±)-kumausallene. Georg Thieme Verlag Stuttgart, New York.

The general zinc-catalyzed allenylation of aldehydes and ketones with an allenyl boronate is presented. Preliminary mechanistic studies support a kinetically controlled process wherein, after a site-selective B/Zn exchange to generate a propargyl zinc int
