• Application of Baylis–Hillman Methodology in the Synthesis of Coumarin Derivatives
  作者：Perry T. Kaye、M. A. Musa

  DOI：10.1081/scc-120018937

  日期：2003.1.6

  Abstract A general, chemoselective approach to 3-substituted coumarins via Baylis–Hillman reactions of O-benzylated salicylaldehyde precursors has been demonstrated. Competitive cyclization to chromene derivatives is inhibited by conjugate addition of benzylamine or piperidine to the α,β-unsaturated ester intermediates.

  日期：2014.12

  Synthetic approaches to a series of novel cinnamate ester-AZT conjugates have been explored and a successful pathway has finally been developed. alpha-(Halomethyl)cinnamate esters, obtained in high yield by treating benzyl-protected salicylaldehde-derived Baylis-Hillman adducts with acetyl bromide at low temperature, have been treated with propargylamine to afford substrates for click chemistry reactions with azidothymidine (AZT) in the presence of in situ generated Cu(I) catalyst to produce the title compounds.

  The relative merits of two different Baylis-Hillman approaches toward the preparation of coumarin derivatives, containing peptide-like side chains, have been explored. In one approach, use of methyl acrylate as the activated alkene requires a protecting group strategy, an approach that is not necessary when using tert-butyl acrylate.

  Halogen acid-catalysed deprotection and cyclisation of Baylis-Hillman products obtained using O-benzylated salicylaldehyde precursors has been shown to afford 3-(halomethyl)coumarins (3-halomethyl-2H-1-benzopyran-2-ones) chemoselectively and in good yield.
