The sterochemistry of the reaction of α-lithio-sulphoxides (α-sulphinyl carbanions) with ketones
Abstract
Metallation of S-benzyl methyl sulphoxide followed by quenching with acetone gives a mixture of diastereomers in a 15 : 1 ratio; the major isomer is shown to have the R configuration of carbon and a synthesis of optically active epoxides from optically active sulphoxdes is described.
