The lithium carbanions of optically pure (+)-(R)-p-tolyl alkyl sulphoxides (5) reacted with lithium bromoacetate and gave (+)-(R)-3-(p-tolylsulphinyl)carboxylic acids (3).Their dimetallation produced a chiral homoenolate dianion equivalent (6) which added
Chiral Homoenolate Anion Equivalents: Synthesis of Optically Pure 5-Substituted Furan-2(5H)-ones

Addition of the dianion of (+)-(R)-3-propionic acid (1) to aldehydes affords two main diastereoisomeric β-sulphinyl-γ-lactones, pyrolysis of which gives the two enantiomers of 5-substituted furan-2(5H)-ones in optically pure for
