A new application of the “mild thiolation” concept for an efficient three-step synthesis of 2-cyanobenzothiazoles: a new approach to Firefly-luciferin precursors
摘要:
An easy, low cost and upscalable three-step synthesis of Firefly luciferin precursors is presented. The 6-alkoxy-2-cyano-benzothiazoles (1) were synthesized starting from easily available O-alkylated 4-aminophenoles (2) via a mild thiolation, Jacobsen cyclization and dehydratization sequence.[GRAPHICS].
