ELIMINATIVE DEOXYGENATION: A FACILE SYNTHESIS OF α-CYANO AND α-CARBOALKOXY SUBSTITUTED VINYL SULFIDES

The facile eliminative deoxygenation of α-cyano and carboalkoxy sulfoxides by trimethylsilyl triflate under mildly basic conditions results in the formation of α-thiophenyl substituted α,β-unsaturated nitriles and esters in high yields.

α-Phenylthio-α,β-unsaturated ketones are prepared in fairly good yields on treatment of α-sulfinyl ketone with stannous triflate. α-Phenylthio-α,β-unsaturated cyanides are also prepared from α-sulfinyl cyanides according to the similar procedure.
THE AdNSNE MECHANISM IN THE REACTION OF PHENOL AND BENZENETHIOL WITH α-BROMO MICHAEL ACCEPTORS IN THE K2CO3-ACETONE SYSTEM

In the reaction of α-bromo Michael acceptors with either phenol or benzenethiol formal substitution of the vinylic bromine proceeds through addition of the phenolic reagent, followed by nucleophilic substitution and β-elimination (AdNSNE mechanism) in the system K2CO3-acetone.The process is shown to be stereospecific in the case of 2a,b and 3b,c, leading to the corresponding Z isomer.The reactivity of substrates 1-4 is discussed in terms of their structural features.
