Abstract

An efficient synthesis of 2,3-disubstituted quinoline derivatives from easily accessible (het)aryl-substituted Morita–Baylis–Hillman (MBH) adducts was achieved by an approach involving a palladium-catalyzed Heck reaction and cyclization. This strategy converts the MBH adducts into α-benzyl β-keto ester derivatives that can cyclize into the corresponding quinolines in good yields.

Key words

quinolines - cyclizations - catalysis - palladium - Heck reactions - tandem reactions

10c Because of the large difference in the pK _a values of DABCO (pK _a = 8.8) and DBU (pK _a = 12), one-pot tandem cyclization and aromatization resulted in decomposition of the starting materials.

11 1,4-Dihydroquinolines 3 and Quinolines 4; General Procedure A mixture of 2-iodoaniline (2a; 2.1 equiv), Pd (OAc)₂ (10 mol%), DABCO (0.6 equiv), and TBAB (2.1 equiv.) in MeCN (2 mL) was refluxed under argon. After 15 min, the MBH adduct 1 (100 mg) was added. When the reaction was complete (TLC), the mixture was allowed to cool to r.t. and filtered through a Celite pad. The resulting mixture of compounds 3 and 4 was subjected to aromatization with DBU and purified by column chromatography (silica gel) to give the quinoline 4.

12 Usually, short-lived H–Pd–I species undergo immediate reductive elimination with a base, but MBH adducts with electron-donating substituents can undergo coupling with H–Pd–I, presumably under the influence of the +I effect of the electron-donating group.
