Total stereospecificity in free radical intramolecular addition : Cyclisation of cis and trans 1-methyl 4-hexenyl N-chloroamines by means of metallic salts
Extremely high stereospecificity (up to 100% diastereoisomeric purity) can be obtained for the metallic salts radical cyclisation of the cis and trans 1-methyl 4-hexenyl N-choloroamines. A possible mechanism for the highly effective trans-addition using metal-complexed aminyl radical is proposed.
