Abstract

A series of potentially bioactive 2H-chromenes have been synthesized in good yields (60–82%) via CuI-catalyzed reactions of alkyl/aryl-(E)-(o-propargyloxy)styryl ketones in an atom-economical approach.

  • 26 Typical Procedure for the Synthesis of (E)-4-(6-Methyl-2H-chromen-3-yl)but-3-en-2-one (9a): A mixture of compound 7a (150 mg, 0.70 mmol), and CuI (14 mg, 10 mol%) was stirred in dry DMF (4 mL) at 100 °C for 2 h. The reaction mixture was cooled to r.t., and then it was poured into H2O (10 mL). The aqueous phase was extracted with CH2Cl2 (3 × 20 mL), the organic layer was washed with H2O (3 × 15 mL), brine (20 mL), and then dried over anhyd Na2SO4. The solvent was removed under reduced pressure to give a crude mass which was chromatographed over silica gel (230–400 mesh) using EtOAc–PE (1:19 v/v) as an eluent to afford the 2H-chromene 9a as a sole product; yield 68%; mp 68 °C.
