Free radical cyclisation of a variety of 1,6-dienes using CCl 4 in the presence of diethyl phosphite or diphenylphosphine oxide has been investigated. These reactions involve addition of the trichloromethyl radical to the diene followed by a 5- exo -

Reaction of primary or secondary alcohols with BrCCl 3 and tetrahydrofuran, usually in the presence of 2,4,6-collidine, leads to the formation of 2-tetrahydrofuranyl ethers in good to excellent yield (56–92%). The reaction mechanism is believed to

Overall 5-endo-trig iodocyclisations of all isomers of the 2-alkenylcyclopentan-1-ols and -cyclohexan-1-ols 11, 12, 14 and 16 have been examined. Only in the cases of the trans-alkenylcyclopentanols 11a and 12a are the reactions either unsuccessful o

Iodoetherifications of all isomers of the 3-methylalk-4-en-2-ols [14∼17] proceed with excellent levels of stereoselectivity, leading to tetrasubstituted tetrahydrofurans [18∼22], via overall anti-addition to the alkene function.
