Synthesis of New Monoarylidenes Derivatives of Limona-ketone: Natural Product Isolated from Cedrus atlantica Oil

Limona-ketone isolated from Cedrus atlantica oil by distillation under reduced pressure was efficiently used as a precursor for the synthesis of newly derived monoarylidenes. Various aldehydes have been used and led to the formation of corresponding compounds in high to excellent yields. The effect of both the nature and the position of the substituted group of the aromatic aldehyde has been investigated.
