Abstract: | Erythrinin A () has been synthesised by the oxidative rearrangement of dihydropyranochalcone with thallium(III) nitrate (TTN) in trimethyl orthoformate (TMOF) to the dimethyl acetal , followed by cyclisation to , demethylation to and dehydrogenation. Compound could also be obtained from chalcone on similar rearrangement followed by cyclisation, demethoxymethylation and dehydrogenation. In another route, chalcone was oxidatively rearranged with TTN in TMOF, to which on treatment with HCl yielded . |
