Synthesis and spectroscopic characterization of some chromanochalcones and their dihydro derivatives

Synthesis of naturally occurring 6-(α,β-dihydrocinnamoyl)-3,4-dihydro-2H-chromanes has been carried out by the reaction of 6-acetyl-3,4-dihydro-2H--chromanes with methoxybenzaldehydes followed by hydrogenation of the resulting 6-cinnamoyl-3,4-dihydro-2H--chromanes
