Synthesis of 3-alkyl-1H-quinolin-2-ones via palladium-catalyzed intramolecular cyclization of benzyl halides and a,b-unsaturated amides.

[摘要]：An efficient synthesis of 3-alkyl-1H-quinolin-2-ones was achieved in high yield (up to 91%) via Pd2(dba)3-catalyzed intramol. cyclization of benzyl halides and electron-deficient olefins, followed by treatment with DBU.
