Abstract:
A novel synthetic method to prepare chalcones 2 and chroman‐4‐ones 3 by TMSOTf‐promoted addition of alkynes 1 to various aldehydes has been developed. The ratios of chalcones 2 , chroman‐4‐ones 3 and hydrated products 4 varied depending upon the substituents R ( n Bu, phenyl, H and TMS) on the alkynes 1 . We also describe the transformation of the chalcones 2 to the corresponding chroman‐4‐ones 3 under basic conditions. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
