Metal-free intramolecular cyclopropanation of alkenes through iodonium ylide methodology
作者:Robert M. Moriarty、Sachin Tyagi、Mark Kinch
DOI:10.1016/j.tet.2010.05.005
日期:2010.7
Intramolecularcyclopropanation of alkenes occurs thermally with iodoniumylides in the absence of conventional metal catalysts such as Rh(II) and Cu(II). In rigid molecular systems conversions are near quantitative. A mechanism is proposed involving formal 2+2 cycloaddition followed by reductive elimination of PhI to yield the cyclopropane.

1-Acetyl- and 1-isopropenyl-3-methylenecyclobutane (I and II) were prepared and then subjected to pyrolysis. The pyrolysis of I at 304–340°C gave 2-methyl-5-methylene-Δ2-dihydropyrane, which was then converted to 4-methylenecyclohexanone at this temperature. The pyrolysis of II at 255–340°C gave 1-methyl-4-methylenecyclohexene, which was disproportionated at this temperature to p-xylene and 1,4-dimethylcyclohexene
