Highly stereoselectivesyntheses of (E)- and (Z)-α-substituted c innamates have been achieved by dehydration reaction of anti- and syn-α-substituted-β-hydroxyphenylpropionates with EDC in good yields. This facile method has been applied to the stereoselectivesyntheses of (E)- and (Z)-α-alkylidene-γ-butyrolactones.
