Abstract: A convenient one-pot preparation of 2-methyl-3-(phenylthiomethyl)quinolines from Morita-Baylis-Hillman adducts via conjugate addition of thiols followed by reductive cyclization with Fe/AcOH was developed. The 2-methyl-3-(phenylthiomethyl)quinolines were transformed into 2-methyl-3-(phenylsulfonylmethyl)quinolines via m-CPBA-mediated oxidation.
Keywords: one-pot procedure; Morita-Baylis-Hillman adducts; quinolines; reductive cyclization; Fe/AcOH
