Ultrasound assisted synthesis of 6-flavonyl substituted 1,4-dihydro-benzo[d][1,3]oxazin-2-ones via Suzuki–Miyaura coupling under Pd/C catalysis

Ultrasound assisted synthesis of 6-flavonyl substituted 1,4-dihydro-benzo[d][1,3]oxazin-2-ones via Suzuki–Miyaura coupling under Pd/C catalysis

Pd/C facilitated Suzuki–Miyaura coupling of 2-aryl-3-bromoflavones with 4,4-disubstituted (1,4-dihydro-2-oxo-2H-3,1-benzoxazin-6-yl)boronic acids under ultrasound irradiation. The methodology involving the use of 10%Pd/C-TBAB-K2CO3 system in DMF/H2O afforded corresponding 6-flavonyl substituted 1,4-...
