Synthesis of 2',6'-Dihydroxychalcones by Using Tetrahydropyran-2-yl and Trialkylsilyl Protective Groups; the Crystal Structure Determination of 2',6'-Dihydroxy-2,4,6-trimethoxychalcone

Two improved general routes to 2',6'-dihydroxychalcones are described in which the final step is protective-group removal from O 2' under mild acid conditions.The first involves base-catalysed condensation of benzaldehydes with 2'-hydroxy-6'-tetrahydropyr
