Article abstract of DOI:10.1246/bcsj.66.1743

The Optically active 3,3-dialkyl-4-thianones 3 and 4 were prepared in moderate yields with about 90percent enantiomeric purity using an asymmetric process involving a Michael-type alkylation of chiral 3-alkyl-4-thianimines with methyl vinyl ketone or meth
