Pt-Catalyzed Rearrangement of Oxaspirohexanes to 3âMethylenetetrahydrofurans: Scope and Mechanism
A novel
Pt-catalyzed rearrangement of oxaspirohexanes to 3-methylenetetrahydrofurans
is reported. Mechanistic studies by <sup>13</sup>C-labeling experiments
confirm oxidative addition of PtÂ(II) regioselectively to the least
substituted carbonâcarbon bond of the cyclopropane to form
a platinacyclobutane intermediate. To our knowledge, this is the first
alkoxy-substituted platinacyclobutane that has been observed spectroscopically.
The scope and a proposed mechanism of this new Pt-catalyzed transformation
are described
