Ride the (micro)wave: The title strategy has been developed for the synthesis of various symmetric or unsymmetric hydroxylated stilbenoids utilizing 4-halophenols and acrylic acid as coupling partners (see scheme; DMA=N,N-dimethylacetamide, MW=microwave). Protecting groups are not necessary and a single palladium catalyst is used. Copyright

All in one: A tandem strategy has been developed wherein secondary aryl alcohols are directly coupled with aryl halides to provide stilbenoids through a dehydrative Heck sequence in the ionic liquid [hmim]Br, and with water as a by-product under microwave irradiation (see scheme). Classical methods do not permit this sequence to proceed in one pot, and some methods require multiple steps. hmim=1-n-hexyl-3-methylimidazolium. Copyright
