The enantiomers of 1-aryl-, 1-alkyl- and 1-alkoxy-3-methyl-3-phospholene 1-oxides were separated in good yields and in high enantiomeric excesses (up to > 99% ee) by resolution via formation of diastereomeric complexes with (–)-(4R,5R)-4,5-bis(diphenylhydroxymethyl)-2,2-dimethyldioxolane (TADDOL) or (–)-(2R,3R)-α,α,α′,α′-tetraphenyl-1,4-dioxaspiro[4.5]decan-2,3-dimethanol.
