An Efficient Approach to the Synthesis of Ethyl α-Cyanoalkyl β-Substituted Acrylates by the HWE Olefination of Ethyl 2-(Diethoxyphosphoryl) Cyanoalkanoates
摘要:
Ethyl -cyanoalkyl -substituted acrylates 5a-i were prepared in good yields on a synthetic scale by Horner-Wadsworth-Emmons olefination of the corresponding ethyl 2-(diethoxy-phosphoryl) cyanoalkanoates 3a-c using different aldehydes and anhydrous potassium carbonate in dry THF at reflux.
