Isoxazolones Knoevenagel reaction

Pyrazolones (154) and isoxazolones (155) can also be used in the Knoevenagel reaction. Thus condensations with aliphatic aldehydes, aromatic aldehydes and ketones in the presence of ethylenediammon-ium diacetate or other typical catalysts provide the corresponding alkylidene and benzylidene compounds in good yields (for stereochemistry see Section 1.1A new method involves the use of dicyclohexylcarbodiimide at 20 C without an additional catalyst. ...
