A reaction of bis(iodozincio)methane with acyclic enones proceeded in 1,4-addition manner to afford zinc enolate of β-zinciomethylketone. In the case of the 1,4-addition reactions of bis(iodozincio)methane with 2- cyclohexen-1-one, an assistance by copper
Synthesis of medium-sized bicyclic compounds by intramolecular cyclization of cyclic β-keto radicals generated from cyclopropanols using manganese(III) tris(pyridine-2-carboxylate) and its application to total synthesis of 10-isothiocyanatoguaia-6-ene

, p. 85 - 97 (1999)
Bicyclic cyclopropanols having an olefinic side chain are oxidized-with manganese(III) tris(pyridine-2-carboxylate) to generate cyclic β-keto radicals with ring-expansion. These cyclize intramolecularly, affording bicyclic radical intermediates. The cycli

Various ring-fused cyclopropyl silyl ethers with an benzylic, olefinic or acetylenic side chain have been synthesized. Upon oxidative photoinduced electron transfer (PET) the cyclopropane ring opens and forms a reactive β-keto radical, which undergoes intramolecular cyclization. In some cases we observed only formation of ring opened non-cyclized products. With olefinic side chain 5-exo-trig mode of cyclization rather than 6-endo-trig mode of cyclization takes place whereas in case of acetylenic side chain we observed 6-endo cyclization.
