Optically active 3-hydroxybutyric and 3-hydroxyhexanoic acids were tra
nsformed into 3,4-disubstituted and 3,3,4-trisubstituted 2-oxetanones
using two different approaches. Diastereoselective alkylation was perf
ormed either on dioxanone enolates or on lithoxy-lithium enolates. Som
e recently published unexpected results of alkylation of substituted d
ioxanones were used for the synthesis of a trisubstituted oxetanone.
