Prochiral substituted enediolates undergo diastereoselective alkylation with β-chiral primary iodohydrin derivatives, with selectivities up to 97:3. The most selective reactions occur with dienediolates, but reasonable selectivities can also be obtained with alkyl- and aryl-substituted enediolates. The presence of the lithioalkoxy substituent on the enolate is crucial for selectivity, as is the presence
