One-pot synthesis of 2-arylated and 2-alkylated benzoxazoles and benzimidazoles based on triphenylbismuth dichloride-promoted desulfurization of thioamides

HIGHLIGHTS

  • who: Arisu Koyanagi and collaborators from the School of Pharmaceutical Sciences, Aichi Gakuin University, Kusumoto-cho, Chikusa-ku, Nagoya, Japan have published the research: One-pot synthesis of 2-arylated and 2-alkylated benzoxazoles and benzimidazoles based on triphenylbismuth dichloride-promoted desulfurization of thioamides, in the Journal: (JOURNAL)
  • what: A control experiment was carried out to investigate the reaction pathway and mechanism.
  • how: Using bismuth compounds as desulfurization reagents for synthesizing heteroazoles this paper presents the syntheses of 2-aryl- and 2-alkylbenzoxazoles through the ring-closure reac- tion of 2-aminophenol with . . .
