Synthesis of 3-nitro-1H-indole-2-carboxylic acid ethyl ester derivatives from Baylis-Hillman adducts
A simple and direct synthesis of 3-nitro-1H-indole-2-carboxylic acid ethyl ester derivatives from acetylated Baylis-Hillman adducts of 2-nitrobenzaldehydes is described. Georg Thieme Verlag Stuttgart.
Synthesis of 3-Ethoxycarbonyl-4-hydroxyquinoline W-oxides from the Baylis-Hillman adducts of o-nitrobenzaldehydes
(Matrix presented) The reaction of the Baylis-Hillman adducts 1a-e of o-nitrobenzaldehydes and trifluoroacetic acid at 60-70 °C gave 3-ethoxycarbonyl-4-hydroxyquinoline N-oxide derivatives 3a-e in good to moderate yields.
