The sulfonyl radical-promoted cyclizations of 1,6-unsymmetrical dienes can be totally chemoselective. The addition of tosyl halides to various 1,6-dienes bearing both a nucleophilic and an electrophilic double bond clearly indicates that the attracti

Addition of TsBr to diallyl malonates and allyl methallyl malonates is described. These cyclization reactions exhibit high stereoselectivity and very high regioselectivity. The structure of the reaction products is elucidated using 2D NMR.

Ag (I) mediated persulphate oxidation of various 2-methyl benzoic acids and acrylic acids, co-catalyzed by Cu (II), leads to unsaturated γ-lactones, together with decarboxylation products. Lactonisation proceeds through 1,5 hydrogen transfer from in

Several β-aminothiols prepared from 3-piperideine and different thiiranes react by free radical reactio chemically initiated to yield exclusively 7-thia-1-azabicyclo (4,3,0) nonane derivatives. Even when this process is in competition with a radical
