ON THE PROPERTIES OF SOME SUBSTITUTED α'-LITHIATED α(Z),Y-BUTADIENYL SULFIDES: CYCLISATIONS AND REARRANGEMENTS

Reglier, Marius,Julia, Sylvestre A.

, p. 2319 - 2322 (2007/10/02)

The conditions for the preparation and cyclisation of the title compounds 3 are described.The stability of the intermediate lithio-thiacyclohexenes 4 is shown to depend on the reaction conditions and the substituents R1-R4.The final Products 6, 10 and 7 arise from 4 via sigmatropic rearrangement, a prototropic shift followed by a sigmatropic rearrangement, or the elimination of lithium methanethiolate respectively.
