Abstract
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.
Key words
heterocycles - synthesis - coumarins - 2H -1-benzopyran-2-ones - Baylis-Hillman
reaction
