Diastereoselective Method of Preparing Olefins by Means of the Horner-Wadsworth-Emmons Reaction Using a Particular Phosphonate Which Improves Diastereoselectivity at all Temperatures Including at Ambient Temperature |
摘要 |
The invention relates to a diastereoselective process for the preparation of olefins by the Horner-Wadsworth-Emmons reaction which consists in reacting a specific phosphonate improve the diastereoselectivity at all temperatures including at ambient temperature, with a carbonyl derivative in the presence of a base in an appropriate solvent.
