A convenient and improved Baylis-Hillman synthesis of 3-substututed 2H-1-benzopyran-2-ones
Kaye, Perry T.,Musa, Musiliyu A.
, p. 2701 - 2706 (2007/10/03)
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.
