Highly selective three-step synthesis of rhein in chloroaluminate molten salt: preclusion of the Hayashi rearrangement
An expeditious, three-step synthesis of rhein (2) was optimized starting from bis(N, N-diethyl)-5-methoxybenzene-1,3-dicarboxamide. The key final step, involving deprotection/cyclization of orihobenzoylbenzoic acid 9 in acidic chloroaluminate molten salts
