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.
STEREOSELECTIVE CONVERSION OF LITHIATED BENZYLIC OR ALLYLIC 3-METHYL-1(Z),3-BUTADIENYL SULFIDES INTO CIS-DISUBSTITUTED CYCLOPROPANE COMPOUNDS
