摘要：

A novel combination of metal-mediated transformations is reported, which together constitute a new organic reaction: the coupling of 3-alkynols and alpha-diazoesters to yield tetrahydrofuranylidene esters. The process involves the migratory insertion of a coordinated carbene into a metal-alkyl sigma-bond and, in stoichiometric form, is efficient and pseudocatalytic, starting and ending with (dppe)PtCl2. The reaction, uniquely, can be made catalytic in platinum, but only poorly so.
